Coating material and its cladding performance is the key to the preparation of high quality coating. In this paper, cladding performance, cladding coating morphology, interface diffusion and microstructure of typical alloy powder material were studied, such as self-melting alloy powder, coated composite powder and mixture metal ceramic powder by experiment. The results show that self-melting alloy prepared by atomization technology has well cladding performance which coating with compact microstructure. Composite alloy powder prepared by chemical method technology has poor cladding performance which loose microstructure. Mixed metal ceramic powder has well cladding performance which homogeneous microstructure. Fe-base alloy and Co-base alloy can be achieved diffusion metallurgical combination with the steel substrate.

The supersonic laser deposition (SLD) of diamond/Cu composite powder is studied over a range of laser power. The deposition efficiency, coating microstructure, cohesive/adhesive bonding, phase composition, micro-hardness, and tribological property of the diamond/Cu composite coating are investigated. The results indicate that, as laser power is increased, deposition efficiency initially increases and then declines. The diamond particles distribute uniformly in the composite coating. Due to the increase of velocity ratio and total energy by laser irradiation, the cohesive/adhesive bonding of the composite coating is improved. The composite coating can preserve the phase composition of the origin powders due to the relatively low heat input during the SLD process. Slight oxidation of the Cu powder can be detected in the coatings prepared with high laser power, which has adverse effects on material deposition. The SLD-diamond/Cu composite coating has superior wear-resistance because of low friction coefficient, high micro-hardness, and uniformly distributed diamond particles.

The wear resistance alloy powder, such as Ni60 is essentially Ni-Cr-B-C-Fe quaternary, with Cr providing strength and wear resistance to the Ni-rich solid solution, as well as functioning as the chief carbide former during alloy solidification [7]. Through experimental work, it is noted that LMD of the Ni60-NB-Ag mixed powders on a TA7 can form the composites.…”

Ni60-NB-Ag was firstly used to fabricate composites to increase the wear resistance of TA7 (Ti-5Al-2.5Sn) titanium alloy surface by means of a laser melted deposited (LMD) technique. Experimental results revealed that a large quantity of the interdendritic lamellar eutectics, the nanoscale particles (NP), and the amorphous structure were formed in such composites. During an LMD process, great amounts of Ag were released from the pre-placed layer, which increased the number of the nucleation points, favoring the formation of a fine microstructure and also the NP. However, too high Ag content led the micro-cracks to be produced. Compared with a TA7 substrate, an improvement of the wear resistance was observed for such LMD composites.
