Summary: | The article describes phenomena which occur in the transitional area between stainless steel and aluminium bronze in laser deposited functionally graded structures created via direct joining method with the InssTek MX-1000 machine. The results of the research demonstrated absence of cracking achieved after changing of the synthesis scheme with the same materials and the same treatment regimes. The sources of cracking on a border between stainless steel and aluminium bronze layers were defined during the research. The results of microhardness measurement of the deposited multilayer structures demonstrated 266 HV maximum value with 43 GPa Young’s modulus of elasticity in the same point of a transitional area. Intermetallics forming, dendritic growth, phase composition and microstructure specific properties of laser deposited stainless steel - aluminium bronze functionally graded materials are also observed and described in the article. |
