As a surface coating technique, laser cladding (LC) has been developed for improving wear, corrosion, and fatigue properties of mechanical components. The main advantage of this process is the capability of introducing hard particles such as SiC, TiC, and WC as reinforcements in the metallic matrix such as Ni-based alloy, Co-based alloy, and Fe-based alloy to form ceramic-metal composite coatings, which have very high hardness and good wear resistance. In this paper, Ni-based alloy (Colmonoy 227-F) and Tungsten Carbides/Cobalt/Chromium (WC/Co/Cr) composite coatings were fabricated by the multilayer laser cladding technique (MLC). An optimization procedure was implemented to obtain the combination of process parameters that minimizes the porosity and produces good adhesion to a stainless steel substrate. The optimization procedure was worked out with a mathematical model that was supported by an experimental analysis, which studied the shape of the clad track generated by melting coaxially fed powders with a laser. Microstructural and microhardness analysis completed the set of test performed on the coatings.

Shock Processing

In order to study the application of laser cladding and laser shock processing (LSP) combinatorial treatment technology, the laser cladding samples of TC4 titanium alloy was shocked by pulse laser, then the surface residual stress, the fatigue life were compared with those without LSP in this paper. High cycle tension-compression fatigue tests were carried out in laser cladding titanium alloy before and after LSP treated. The results indicate that LSP treatment can improve the high cycle fatigue endurance limit of laser cladding titanium alloy effectively. The nano-crystal grained surface layer with residual compressive stress makes great contributions to the improvement in fatigue properties of titanium alloy.
