钴基合金堆焊层裂纹成因及控制措施
Causes and Control Measures of Cracks on Co-based Alloy Overlay
摘要
Abstract
Co-based alloy is of a special microstructure with excellent properties so as to be widely used in various industries.However,different defects on Co-based alloy overlay have been reported while welding or operate an equipment with Co-based alloy because of a poor weldability from this alloy,one of which is the cracks.The cracks have been proved to show a most negative impact on an equipment.This pa-per is developed to study the crack morphology and its causes.Thus some miscellaneous cases on Co-based alloy were specially analyzed and described,and the typical basic laws and usual methodology causes were raised and finally some suggestions to limit the cracks on Co-based alloy overlay were summarized.关键词
