Thermal spraying of light alloys
C.J. Li, Xi’an Jiaotong University, China
Thermal spray coatings have been widely applied to add functions such as wear resistance, corrosion resistance, bioactivity and dielectric properties to light metals. The characteristics of the deposition process, involving splat cooling and successive stacking of splats, create coatings of unique microstructure which are different from conventional materials. In this chapter the characteristics of the thermal spray processes, and factors influencing spray particle parameters are described. The metal alloy particle oxidation, splat formation (including solid–liquid two-phase droplet impact involved in cermet coating deposition) and features of the pores ...
