摘要
选用了三种铸铁基材和四种合金粉末，考察了激光能量密度（ｑ）以及各种基材与合金粉末搭配时对熔覆裂纹的作用。建立了一种定量评判基材与粉末材料相容性的公式，由该公式可计算出湿润角。和ｑ是控制裂纹形成与否的两个重要原因。
AbstractThree cast iron materials and four alloy powders are used to investigate the effects of thelaser specific energy(q)and the various matching beteween the matriX materials and alloy pow-ders on the cladding cracks.To quantitatvely evaluate the compatibility between the matrixmaterial and powdet,a formula has been given,by which the wetting angle can be calcula-ted.and q are the two important factors to control the forming of cracks.
