Ｎｉ含量对Ｆｅ－Ｃｒ－Ｎｉ合金激光熔覆层性能及开裂敏感性的影响宋武林，朱蓓蒂，曾晓雁，崔昆（华中理工大学）金属涂层开裂是激光熔覆工艺中一个难题。发生开裂的主要原因是涂层形成过程中产生的各种应力，其中包括热应力、组织应力和拘束应力。这些应力的大小多与涂... Effect of Ni Content on Properties and Cracking Sensitivity of Laser Cladding Layer for Fe-Cr-Ni Alloy SONG Wu-Lin, ZHU Bei-Ti, ZENG Xiao-Yan, Cui Kun (Huazhong University of Science and Technology) The cracking of metal coating is a difficult problem in laser cladding. Cracking occurs mainly due to the various stresses that occur during the coating formation, including thermal stress, microstructural stress and restraining stress. The size of these stresses and painted ...
