High Nickel

This paper presents an investigation on laser direct metal deposition of tool steel on copper alloy substrate both directly and using high nickel stainless steel as buffer layer. The bond strength between the clad and the substrate has been investigated. Tensile testing was employed to measure the bond strength. The characteristics of the fracture surfaces have also been analyzed. Bond strength measurement revealed that the ultimate tensile strength of the substrate material was higher compared to the bond strength between the clad and the substrate. In addition, the experimental result revealed that use of high nickel stainless steel reduced the bond strength with substrate. However, the bond strength measured in this experiment between laser cladded tool steel and copper alloy substrate was much higher compared to the bond strength between these two metals coated using other techniques.

Hardness Values

This paper presents an investigation on the microstructure and surface hardness of the parts fabricated by laser assisted Direct Metal Deposition (DMD) technology. A series of engineering metallic alloy powders were used in the DMD process to produce simple 3D geometric structures. The alloy powders investigated include: 316L stainless steel, 420 Stainless Steel, Stellite(R) 6, tool steel (H13), Cholmoloy (Ni Based alloy), and Aluminium Bronze. These were chosen due to their frequent application in engineering parts and components. The microstructure and hardness values have been compared to those of the wrought products (as annealed) as reported in the SAE standards, Heat treater’s guide to metals ASM international, and material data sheets supplied by the materials manufacturers. A significant difference is reported in both hardness and microstructure of the laser deposited samples compared to those of the wrought form.
