Abstract

The present application relates to a coating preparation system, which is used to prepare a coating on the surface of a workpiece, including: a power supply, a laser, a controller, and a micro-arc oxidation device; the controller is respectively connected to the power supply and the laser; the power supply The anode of the anode is connected to the micro-arc oxidation device, and the negative electrode is connected to the cathode of the micro-arc oxidation device; the controller controls the laser to preheat a part of the anode; the controller controls the power supply and the laser The preheated anode was subjected to laser arc coupled micro-arc oxidation. In this application, the anode is preheated by the laser outputting the second pulse, and the controller controls the laser and the power supply to perform laser arc coupling micro-arc oxidation, so that the second pulse of the laser and the third pulse of the power supply are in a synchronous sequence, making the prepared coating more efficient uniform.

Description

technical field [0001] This application relates to the technical field of material surface treatment engineering, in particular to a coating preparation system. Background technique [0002] In recent years, magnesium alloys, titanium alloys and other metals have been used more and more as medical implant materials, such as human implants and cardiovascular and cavity interventional therapy stents, etc., which have high medical value and broad application market. However, the poor corrosion resistance of magnesium alloys and titanium alloys restricts their application and promotion. [0003] Micro-arc oxidation (MAO) is an emerging material surface modification technology. By controlling its electrical parameters and electrolyte composition, it can grow a substrate with strong bonding force, high hardness and wear resistance on the surface of magnesium alloy and titanium alloy. Ceramic coatings with high corrosion resistance and high corrosion resistance are conducive to br...
