Comparison of mechanical properties of laser cladded WC and (TIW)C1-X IN NI based alloy coatings

For wear demanding applications, the metal matrix composites (MMC) are often used due to their high wear resistance, and the tungsten carbide is often used as hard reinforcing particles. Nevertheless, there are still some limits of WC, mainly its deterioration due to heat load ...

Microstructure, tribological behaviour and xrd analysis of hvof sprayed and laser remelted cocrtaalcsiy coatings

Superalloys with cobalt as a base material are widely used among different industry applications. Their main advantages are excellent corrosion and wear resistance. Material CoCrTaAlCSiY was chosen for this study as an unexplored representative of Co-based superalloys with a potential for go...

Corrosion resistance of laser-deposited composite copper-basalt overlay

This paper deals with an assessment of the corrosion resistance of copper-basalt composite cladded by laser. The filler powder for laser overlaying was a mixture of high-purity copper powder Oerlikon METCO 55 consisting of 45–90 µm particles and a basalt powder comprising particles 50–2...

Chemical heterogeneity of Inconel 625 overlay with an increased molybdenum content and its evaluation using the potentiodynamic corrosion test

The paper focuses on a detailed analysis of chemical heterogeneity of Inconel 625 overlays with an increased molybdenum content deposited by laser cladding. Fifteen samples of laser overlays on S355J2 steel were prepared, each with an area of 90×140 mm. The thickness of the steel&#...

Application of flash-pulse thermography methods for quantitative thickness inspection of coatings made by different thermal spraying technologies

Flash-pulse thermography is a nondestructive testing method, which is based on thermal excitation and response analysis of a tested sample. It is the traditional method for a non-destructive inspection of discontinuities and inhomogeneities at a sample surface, which is also applicable for&#...
