Abstract

Pseudo alloys are composite materials produced by various methods from the metal phases insoluble in each other. The components of pseudo alloys, as a rule, are sharply distinguished by their physicomechanical properties. In this paper, the method of deposition of coatings with a pseudo-alloy structure by the method of electric arc metallization is studied. The main factors influencing the structure of coatings are determined, and the data obtained during metallographic studies of coatings sprayed are presented. The effects of heat released at the cathode and anode on the shape of the melting fronts of the wires are studied. It is determined that, with a significant difference in the specific thermal energy and an unsuccessful choice of the polarity of the electrodes, the melting of the wires is uneven and will cause a significant separation of metals in the coating. The paper shows that the use of more refractory wire as a cathode leads to separate deposition of droplets of dissimilar metals. In addition, the microhardness of the resulting pseudo-alloy coating is investigated.

电弧金属化沉积伪合金涂层

摘要

伪合金是通过各种方法由彼此互不溶的金属相生产的复合材料。通常，假合金的成分可以通过其物理机械性能来明显区分。本文研究了利用电弧金属化方法沉积具有伪合金结构的涂层的方法。确定了影响涂层结构的主要因素，并给出了在喷涂涂层的金相研究过程中获得的数据。研究了在阴极和阳极释放的热量对焊丝熔化前沿形状的影响。可以确定，由于比热能存在显着差异，并且电极的极性选择不成功，导线的熔化不均匀，会导致涂层中的金属大量分离。该论文表明，使用更多的耐火线作为阴极会导致异种金属液滴的单独沉积。另外，研究了所得伪合金涂层的显微硬度。
