摘 要:对比了国产与进口不锈钢带极性能的优劣,采用相同工艺参数对国产和进口带极进行双层带极堆焊对比试验,焊后检验表明,国产带极的堆焊层力学性能、耐腐蚀性能基本满足标准要求,但国产不锈钢带极的C、P、S质量分数较高,Nb/C较低,影响了堆焊层的耐腐蚀性能。同时,国产带极的尺寸精度、表面粗糙度和硬度不能满足要求,需要进一步改进。By means of contrasted experiments of the performance and the procedure for domestic and import stainless strip electrodes in the same surfacing processes are studied.The test results indicated that the mechanical property and corrosion property of the domestic layer content the requirements basically.But the content of C,P and S of it is much higher and Nb/C is not enough,so it has some disadvantages for the corrosion and the dimensional accuracy,the surface smoothness and the hardness can't content the requirements.Some suggestions were given to solve.
