AI Technical Summary

Problems solved by technology

When the tip grain absorbs the film layer, due to the small contact area, the film layer molecules are easy to gather at the tip. In severe cases, the particle (particle) exceeds the standard or the tip arcing (discharge) is abnormal during the use of the equipment, which affects the normal use of the component. cycle

Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings.

[0021] In the polishing process of the ARC spray layer mentioned in the present invention, the removal of grains at the tip of the spray layer and the optimization and improvement of the roughness can be completed by using pneumatic polishing equipment and 7447# scouring pad. The specific implementation process is as follows:

[0022] 1. Body sandblasting: use 24# white corundum (WA) sand material to sandblast metal (aluminum alloy, stainless steel, titanium alloy, etc.) samples (including sample 1, sample 2 and sample 3) of appropriate size, adjust the The sand pressure and operation method make the surface roughness of the parts after sandblasting uniform, and the roughness Ra value ranges from 6 to 13 μm;

[0023] 2. Cleaning: For parts after sand blasting, rinse with deionized water and ultrasonic cleaning (10inch / cm 2 , 15min), remove the residual sand material ...

Abstract

The invention provides a control method for electric arc technology aluminum meltallizing layer surface tip surface burrs. A scouring pad polishing piece is installed on pneumatic polishing equipmentfor polishing a meltallizing area, and the polishing pressure is controlled to be 3-5 Kg / CM<2> to evenly polish the surface of a component, tip grains on the surface of the component can be effectively removed, and the lowest ARC meltallizing roughness degree is controlled and adjusted to reach 16.781 micormeters.

Description

technical field [0001] The invention relates to the field of electronics industry, in particular to a method for controlling tip burrs on the surface of an aluminum fusion spray layer in an electric arc process. Background technique [0002] Melt spraying is a surface thermal spraying treatment technology. On the surface of the substrate after a series of pretreatments such as sandblasting and cleaning, the molten spray coating droplets are sprayed by airflow, and the mechanical combination of coating cooling and spreading is used. Force, covering a relatively uniform and rough coating on the surface of the substrate. [0003] The semiconductor physical vapor deposition (sputter) process will adsorb a certain thickness of sputtering substances such as metals, oxides, and organic substances on the surface of the part. For defects such as (particles) abnormalities, spraying treatment will be used in the cleaning and regeneration process of parts. ARC spraying is arc spraying...
