Presented at PICALO 2008
With preplaced Ti6Al4V + Cr3C2 powder mixtures, the Ti-base composite coatings with in-suit synthesis TiC were obtained by laser cladding on Ti6Al4V substrate. The effects of the ceramic phase (TiC) and the matrix on microhardness of the coatings were also studied by addition of TiC, Cr and Mo into the coatings respectively. The results showed that, t...$28.00

Presented at PICALO 2008
Titanium alloys are used on aeronautical engine widely. In order to improve the surface properties of titanium alloy part to meet the requirements of fiction and wear properties, a functional graded cladding layer (Ti-FGCL) on Ti600 was successfully carried out by an experimental of laser multi-claddings. Powder mixtures are pre-placed on samples or cladding layer, the main components of Ti, Ni, Al, and Cr3C2 are changed from the bottom layer to top. A 4kw cw CO2 laser is used to clad every layer. SEM and EDAM are used to analyze micr...$28.00
