Abstrakty : The Ni-Co based coatings were performed by means of PTA method from Ni-based and Co-based powders. The cavitation erosion resistance of Ni-Co specimens and reference sample in deionized water was determined by the ultrasonic vibration system. The microstructure, as well as mechanism of cavitation erosion of coating was examined by using SEM and LOM. The main mechanism of erosion is cracking and spalling at the boundary of dendrites and eutectics. Coatings exhibit higher cavitation erosion resistance than the reference sample. Therefore, they could be applied to repair and protect pump elements from cavitation wear.

Abstrakty : A series of cavitation erosion tests were carried out to investigate the resistance of the TiN coatings to cavitation action. The TiN coatings were deposited at various deposition parameters on austenitic stainless steel, X6CrNiTi18-10, and with various thickness by means of the cathodic arc evaporation method (ARC PVD). Investigations were performed in a cavitation tunnel with a slot cavitator. The investigations show that hardness, Young’s modulus, adhesion and coating thickness have an influence on coating endurance to cavitation degradation. The obtained parameter H•LC2/E•h1/2 shows very good fitting to date points (R2=0.96). With the increase of the H•LC2/E•h1/2 parameter the mass loss decreases indicating a continuous improvement in the cavitation erosion resistance.

Abstrakty : In the paper the investigation of cavitation resistance of Fe-Cr-Mn coating has been shown. This alloy is used in mending of machine elements subjected to cavitation. Chromium nickel stainless steel 0H18N9 was used as the substrate. Clad was tested for three cases: without additional processing, after laser heating of the solid state and after laser melting of the coating. CO2 laser with a beam power 1000 W was used as a source of radiation. The investigated sample was exposed to cavitation loading at the rotating disk facility. The investigations were performed in the initial period of the clad damage. The plastic deformation on the investigated surfaces was defined using an image analysis. The microstructure, chemical composition and phase identification of the modified layer were examined using scanning electron microscopy (SEM), light microscopy (LM), energy dispersive X-ray spectroscopy (EDX) and X-ray diffractometry (XRD), respectively. The hardness of processed layers was investigated by a Vicker hardness tester. The results indicate, that there is different susceptible to plastic deformation caused by cavitation loading for different kind of laser processing.

Abstrakty : In the work, the relationships between cavitation resistance of laser produced alloys and their ability to work hardening were searched for. Considerations were carried out for groups of samples with surface layers featured by one common property, such as brittleness, hardness or uniformity of the laser processed zones. It was found, that materials of approximate surface microhardness exhibit monotonical rela-tionship between erosion resistance and the ability to work hardening. .

Abstrakty : In the work, the dependence of cavitation resistance of laser produced of electrode produced superticial iron alloys on the type of the substrate was investigated. Substrates of tested samples were made of steels 45, 2H13, OH 18N9T and Armco iron. Cavitation assays of the materials with thin surface layers alloyed with SiC or AlNi compounds or with 1-2,5 mm thick coatings deposited by means of electrodes IMP6 and IMP9 were carried out. It was found, that substrate play significant role in erosion resistance of superficially processed steels due to surface processing effect petrified in the course of the thermal cycle.

Abstrakty : In the paper the investigations of cavitation erosion of 2H13 and 1H18N9T steels superficially remelted by laser beam arepresented. The experiments were carried out at the incubation period of the erosion. Rotating disk facility was used for generation of the cavitation loading. Influence of the parameters and processing condi-tions on the increase of cavitation erosion resistance was assessed. It was established that martensitic structure in 2H13 steel, created due to rapid cooling within the narrow path of the remelting did not lead to durable improvement of the metal resistance to cavitation attack. It was also stated, that strain-hardening of the remelted layer manufactured in 1H18N9T steel as well as the residual stresses relaxation in course of the pulse radiation processing are most profitable for increasing of the caviation resistance of the latter material.

Abstract : The cavitation attack can cause various damages of the material, depending on cavitation intensity. Herein the relationships between cavitation intensity and the changes of microstructure of aluminium-magnesium alloy are presented. Correlation between energy flux density and mass erosion rate is de-scribed by simple empirical mathematical expression: ER = 1E – 05 J 2 + 0,0005 J, where: J – energy flux density, ER – cavitation erosion rate. Here it is shown that for the intensity of cavitation J<2 mW/m2 the duration of the incubation period is invariable, while at the cavitation intensity J>1 mW/m2 its duration decreases with increasing energy flux density J.

Abstrakty : In the paper the investigations of cavitation erosion of 2H13 and 1H18N9T steels superficially remelted by laser beam arepresented. The experiments were carried out at the incubation period of the erosion. Rotating disk facility was used for generation of the cavitation loading. Influence of the parameters and processing condi-tions on the increase of cavitation erosion resistance was assessed. It was established that martensitic structure in 2H13 steel, created due to rapid cooling within the narrow path of the remelting did not lead to durable improvement of the metal resistance to cavitation attack. It was also stated, that strain-hardening of the remelted layer manufactured in 1H18N9T steel as well as the residual stresses relaxation in course of the pulse radiation processing are most profitable for increasing of the caviation resistance of the latter material.

Abstract : The cavitation attack can cause various damages of the material, depending on cavitation intensity. Herein the relationships between cavitation intensity and the changes of microstructure of aluminium-magnesium alloy are presented. Correlation between energy flux density and mass erosion rate is de-scribed by simple empirical mathematical expression: ER = 1E – 05 J 2 + 0,0005 J, where: J – energy flux density, ER – cavitation erosion rate. Here it is shown that for the intensity of cavitation J<2 mW/m2 the duration of the incubation period is invariable, while at the cavitation intensity J>1 mW/m2 its duration decreases with increasing energy flux density J.

Abstract : In this paper some results of cavitation erosion studies of various constructional steels (15GA, 15HN, 45, 2H13) processed superficially by laser beam are pre-sented. The erosion tests were carried out by using the rotation disk facility. Con-stant values of the erosion rate were found for each stage of the material damage. Proposition of the evaluation of the relative cavitation erosion resistance of laser processed materials in the incubation period of damage consisted in direct compar-ing of the constant rates of the erosion.

Abstract : The cavitation attack can cause various damages of the material, depending on cavitation intensity. Herein the relationships between cavitation intensity and the changes of microstructure of aluminium-magnesium alloy are presented. Correlation between energy flux density and mass erosion rate is de-scribed by simple empirical mathematical expression: ER = 1E – 05 J 2 + 0,0005 J, where: J – energy flux density, ER – cavitation erosion rate. Here it is shown that for the intensity of cavitation J<2 mW/m2 the duration of the incubation period is invariable, while at the cavitation intensity J>1 mW/m2 its duration decreases with increasing energy flux density J.
