Ultrasonic flame painting system and manufacturing method of iron-based amorphous coating

Abstract

The invention discloses an ultrasonic flame painting system and a manufacturing method of a high-quality iron-based amorphous coating. The ultrasonic flame painting system comprises an ultrasonic flame spray gun and air cooling equipment; the air cooling equipment comprises a base, a cooling table and a storage cylinder; the cooling table is a hollow structure which is internally provided with a cavity; multiple air outlets which communicate with the internal cavity of the cooling table are formed in the cooling table; the storage cylinder communicates with the internal cavity of the cooling table; a solenoid valve is arranged on an air inlet pipe; a temperature sensor is further arranged on the cooling table; the temperature sensor is used for monitoring painting temperature; when the high-quality iron-based amorphous coating is manufactured, temperature of a base plate in the painting process is monitored by the temperature sensor in real time; the flow of cooling air entering the cooling table is controlled by the solenoid valve, so that the temperature of the base plate is precisely adjusted during the painting process; the amorphous coating with high density and high amorphouscontent is obtained; painting efficiency is greatly improved; and the high-quality iron-based amorphous coating can be effectively manufactured.

Description

technical field [0001] The invention relates to the technical field of amorphous coating spraying, in particular to a supersonic flame spraying system and a method for preparing a high-quality iron-based amorphous coating. Background technique [0002] At present, the service life of many structural parts is greatly reduced due to poor anti-corrosion and wear resistance under harsh conditions. Therefore, surface protection is required to prolong their service life. Supersonic flame spraying is used to spray iron-based amorphous coating on the surface of the workpiece. , can effectively improve the anti-corrosion and wear resistance of the workpiece, but the temperature of the substrate will rise rapidly during the spraying process, which will seriously affect the amorphous content of the prepared coating, and the spraying efficiency will also be greatly affected. Therefore, by designing a set of air-cooling equipment to cool the substrate during the spraying process and prec...

AI Technical Summary

Problems solved by technology

Since the spraying process is simply air-cooled, real-time monitoring of the substrate temperature cannot be achieved by controlling the air flow, which greatly affects the density or amorphous content of the coating, and the spraying efficiency will also be reduced

This is because the temperature of the substrate cannot be mon
