摘要

研究了间接电弧和直接电弧的等离子喷涂过程。利用等离子体加速器直接电弧的功率脉冲调制，在等间距区域内对涂层进行局部熔透，从而实现涂层的强化。提出了理论上估计的强化模式、提供涂层焊透至涂层基底过渡区和满足表面开采载荷的强化模式。

Strengthening of plasma-spraying coats by power impulse modulation of plasmatron direct arc

Plasma-spraying process with the use of indirect and direct arcs is taken up. The coat strengthening is realized by local weld penetration of the coat in equally spaced zones by power impulse modulation of the plasmotron direct arc. Theoretically estimated modes of strengthening, providing coat weld penetration till the transition zone of the coat base and satisfying the surface exploitation loads are presented.
