Abstract

The results of testing the "brass" type coating under conditions of oil lubrication I-20A with additives of the metal-coating additive "Valena" at a specific pressure of up to 130 MPa are presented. It is shown that additives have no effect on the wear intensity, which is in the range of (0.5...12.0)•10–9 in the load range 314...1882 N. The influence of the phase composition on the tribological properties of the coating and recommendations on the technological parameters of spraying and testing are evaluated.

气动力喷涂“黄铜”型涂层摩擦学性能评价
介绍了在I-20A油润滑条件下,添加金属涂层添加剂“Valena”,在高达130 MPa的比压下对“黄铜”型涂层的测试结果。结果表明,添加剂对磨损强度无影响,在314 ~ 1882载荷范围内,磨损强度在(0.5 ~ 12.0)~ 10 ~ 9之间N.评估了相组成对涂层摩擦学性能的影响以及对喷涂和测试技术参数的建议。
