-uniform compression plastic deformation. In the compress stress condition, the stress of the cladding metal in the pool nearby is equal to zero. The coagulated cladding metal is in the tensile stress... Temperature and stress fields of multi-track laser cladding ZHAO Hong-yun (赵洪运), ZHANG Hong-tao(张洪涛), XU Chun-hua(徐春华), YANG Xian-qun(杨贤群) School of Materials Science and Engineering......
and corrosion. SEM was used to observe the surface topography of the coatings, while the cohesive force between coatings and matrix compress (ambient temperature and above 650 ℃) and neutral electrochemistry... modulus and plateau stress of aluminum foams with Ni coatings are 2.3 and 1.5 times of those without coatings, respectively. Because of Ni coatings, the strength of aluminum foams still exists......
