Negative ion coating spraying system and spraying method thereof

Abstract

The invention discloses a negative ion coating spraying system and a spraying method thereof. The spraying system comprises a bottom plate, a workbench is fixedly arranged in the middle of the upper end of the bottom plate, a clamping mechanism is arranged in the workbench, and the clamping mechanism comprises a first sliding groove, a first sliding block, a tensioning block and a connecting block; a plurality of first sliding grooves are evenly formed in the periphery of the surface of the upper end of the workbench, first sliding blocks are movably arranged in the first sliding grooves in a clamped mode, tensioning blocks are fixedly arranged at the upper ends of the first sliding blocks, connecting blocks are fixedly arranged at the lower ends of the first sliding blocks, a first transmission mechanism is arranged in the workbench, the first transmission mechanism comprises a fixed block, a movable rod, a first transmission block, a first mounting seat, an electric push rod, a movable plate, a second transmission block and a first transmission rod. The spraying system is good in using effect, a deflection electric field is arranged on the outer side of the ion spraying mechanism, the spraying direction can be finely adjusted during ion spraying, and therefore the spraying quality of the device can be improved.

Description

technical field [0001] The invention relates to the field of ion coating, in particular to a negative ion coating spraying system and a spraying method thereof. Background technique [0002] Plasma spraying is a material surface strengthening and surface modification technology, which can make the surface of the substrate have properties such as wear resistance, corrosion resistance, high temperature oxidation resistance, electrical insulation, heat insulation, radiation protection, wear reduction and sealing. Plasma spraying technology uses the plasma arc driven by direct current as the heat source to heat ceramics, alloys, metals and other materials to a molten or semi-molten state, and sprays them on the surface of the pretreated workpiece at high speed to form a firmly adhered surface layer. . Plasma spraying is also used for medical purposes. [0003] When the current plasma spraying device is in use, the ions are often accelerated by an electric field and then hit th...

Problems solved by technology

[0003] When the current plasma spraying device is in use, the ions are often accelerated by an electric field and then hit the raw material for coating spraying, and the coating spraying direction is completely adjusted by the experience of the master or the mechanical arm, so the adjustment effect is not enough Fine, especially in spraying eng...
