Porosity and surface roughness simulation of nickel-aluminum coating in plasma spray forming ZENG Hao-ping(曾好平)1, 3, FANG Jian-cheng(方建成)2, XU Wen-ji(徐文骥)1, ZHAO Zi-yu(赵紫玉)2, WANG Li(王 莉)2 1... of coating porosity and surface roughness of nickel-aluminum alloy (Ni-5%Al) in plasma spray forming was presented, which was based on the multi-dimensional statistical behaviors of the droplets as well......
pressure and electric discharge current heating, the ionized gases were driven through the nozzle outlet and a plasma jet formed[18-19]. The bulk metal Cu was heated and melted and then metal atoms were detached from the metal surface when the plasma jet heating energy exceeded the metal superficial energy, and evaporated into free atom state. Above the evaporation source, there was a region filled......
