摘要
通过正交设计确定等离子弧粉末堆焊工艺参数对堆焊层质量的影响，经过正交多项式回归分析得到Ｆｅ－０７合金粉末在Ｘ６５板材上表面堆焊的最佳工艺参数为Ｉ＝ １８０～１９０ Ａ，Ｇ＝ ４１．５ ｇ／ｍ ｉｎ，Ｖ＝ １０２ ｍ ｍ ／ｍ ｉｎ，Ｔ０ ＝ ３５０ ℃，Ｑ１ ＝ ２８０ Ｌ／ｈ，Ｑｓ＝ ４００ Ｌ／ｈ，并通过裂纹试验得出抗裂预热温度为３５０
The influence of plasma arc powder surfacing technical parameters on the property of the layer is defined using the orthogonal design.By the orthogonal polynomial regression,when plasma arc powder surfacing is used on the surface of an X65 steel plate with the Fe 07 alloy powder,the optimum technical parameters are the following: I =180～190 A, G =41.5 g/min, V =102 mm/min, T 0=350 ℃, Q 1=280 L/h, Q s =400 L/h.Further,analysis of the cracking test data reveal that the cracking preheating temperature is 350 ℃.
