complexity of the components and a requirement for a higher forming limit of the material. A general solution for the new challenges could be the impulsive forming method. Applying impulsive forming... to conduct metal forming process. This forming method is essentially an impulsive forming process and thereafter owns the general advantages of impulsive forming including the improved forming limit......
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... 2006 Abstract: As the important evaluation parameters concerning the spray qualities, the porosity and surface roughness of the coatings obtained by thermal spray forming have great influence......
