Abstract

以316L不锈钢粉末为原料,采用等离子弧沉积技术在高沉积速率下获得了致密无缺陷的单道试样。首先研究了沉积电流、扫描速度、送粉速度与沉积层高度、沉积层宽度、沉积角之间的关系,然后对沉积试样的微观组织和组成成分进行了检测与分析。结果表明:沉积角随着送粉速度的增大而增大,随着沉积电流的增大而减小;沉积角主要是锐角,有利于试样的沉积;沉积电流对沉积层宽度的影响最大,扫描速度对沉积层高度的影响最大,稀释率随着扫描速度的增大而减小,随着沉积电流的增大而增大,随送粉速度增大而减小;沉积试样成分均匀,凝固组织为奥氏体和铁素体。

Other Abstract

In this study, dense and defect-free specimens of a single track are fabricated at a high deposition rate using the plasma arc deposition, in which the 316Lstainless steel powder is used as the deposition material. The effects of the deposition current, scanning speed, and powder feeding rate on the deposition height, width, and angle of the specimens are studied. Moreover, the microstructure and composition of the deposited samples are examined and analyzed. The results indicate that the deposition angle increases with increase in the powder feeding rate and decreases with increase in the deposition current. The deposition angles of the specimens fabricated under different deposition parameters are mainly sharp angles, which is beneficial for the deposition of the lapped samples.  Among all the process parameters, the width of the single track is mostly affected by the deposition current, while its height is mostly affected by the scanning speed. The dilution rate decreases under a higher scanning speed, lower deposition current, or higher powder feeding rate. The composition distribution of the deposition specimens is uniform. The solidified microstructure comprises austenite and ferrite phases.
