Abstract

The invention discloses a plasma surface treating device for an anti-abrasion tamping pick for a railway and a using method thereof, and relates to a surface treatment device and a using method thereof. The problems of complicated technology for treating the surface of the anti-abrasion tamping pick for the railway and the difficulty in guaranteeing the performance are solved. The device consists of a cooling water channel, an argon-nitrogen mixture gas channel, a high temperature resistance ceramic element, a tamping pick head reservation port, a high temperature resistance sealing piece, a vacuum pump air extraction channel, a detachable stainless steel plasma generator entity and a reaction chamber. The using method comprises the following steps of: 1, putting the tamping pick into the reaction chamber, sealing and vacuumizing the chamber; 2, filling argon and nitrogen into the reaction chamber, applying square negative pulse voltage to ionize argon and nitrogen mixed gas, and forming nitrogen-containing high temperature plasmas; and 3, hitting the surface of the tamping pick to form a modified layer, namely finishing surface treatment for the tamping pick. The device and the using method thereof are applied to the field of surface processing.

Description

technical field [0001] The present invention relates to surface treatment devices and methods of use thereof. Background technique [0002] The tamping pick is a consumable part applied to the large-scale railway track maintenance machinery - tamping car. Its function is to tamp and fasten the ballast in the track bed of the railway line, so that the ballast can provide stable and solid support for the sleeper. During the tamping operation, since the ballast bed is a granular structure, the stress on the wear-resistant tamping pick is very complicated, not only by the impact force and friction force, but also by the alternating stress. Therefore, the tamping pick is required to have high wear resistance and sufficient fatigue resistance to achieve good working results and prolong service life. [0003] The surface hardness of the wear-resistant tamping pick can be increased by surfacing and spray-welding the wear-resistant alloy layer on the surface, but the surfacing and s...
