Preventing the formation of brittle intermetallic compounds and defects or porosity in the fusion zone is a major challenge when welding dissimilar materials. Additionally, differences of physical properties between two joined materials generate thermal expansion mismatch stresses on cooling which means these weaknesses can quickly lead to failure. Welding research has not...$28.00

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
