The effect of laser-cladding on the wear behavior of gray cast iron brake disc

This study is concerned with the influence of four metallic reinforcements on aluminum-silicon (AlSi) composites, with respect to wear behavior. AlSi-Ti; AlSi-Ti6Al4V; AlSi-1.4301 stainless steel and AlSi-Ni particulate reinforced composites were produced by a hot-pressing route. Microstructural characterization showed a uniform distribution of the reinforcing particles in the AlSi matrix. Reciprocating pin-on-plate wear tests were performed for AlSi and AlSi-based composites against gray cast iron plates. In order to compare the effect of different metallic particulates on the AlSi-based composites/gray cast iron tribopair wear performance, besides the pin, the counterface was also analyzed. The particle/matrix interface is analyzed in order to understand its influence on the tribopair behavior and on the controlling wear mechanisms. It was shown that the better compromise between both sliding surfaces performance was attained by AlSi-Ni/gray cast iron tribopair.

Aluminium-based TiB2reinforced composite is a promising material to be used as brake drum material, and it may emerge as substitute for conventional gray cast iron. Aluminium-based composites containing 2% by wt copper reinforced with 2.5 and 5 wt% TiB2composites were made in induction furnace by in situ synthesis process using simultaneous addition of halide fluxes (K2TiF6and KBF4). These cast composites were evaluated for microstructures, hardness, flow curve properties, and tensile properties. It was observed that overall wear behavior gave reasonably good correlation with mechanical properties of composites as compared to gray cast iron.
