Problems solved by technology

[0003] The mechanical arm is easily corroded during long-term use. For large mechanical arms, the cost of traditional phosphating treatment is too high, and the film formation time is long, the film formation is loose, the film thickness is uneven, and the hardness is not good. High, the surface is not smooth, and the corrosion resistance is poor. Therefore, a phosphating treatment process for the mechanical arm is currently required

Abstract

The invention provides a phosphating process of a mechanical arm, and relates to the field of metal surface treatment processes. The phosphating process includes the following steps that (1), the mechanical arm is put in a cleaning agent to be cleaned, and the mechanical arm is dried after being subjected to sanding rust removal and washing; (2), the mechanical arm is surface-conditioned through asurface-conditioning agent; (3), the mechanical arm is put in phosphating liquid, and the phosphating liquid is stir-heated to 75 DEG C from 25 DEG C and then subjected to heat preservation for 13-18min, wherein the heating rate is 12-18 DEG C / min, and 0.2 part of phosphoric acid is replenished every time the temperature rises by 10 DEG C in the heating process of the phosphating liquid; and (4), after phosphating is completed, the mechanical arm is flushed with indoor-temperature water, the mechanical arm is soaked in a hot sodium chloride saturated water solution, and the mechanical arm isdried. A phosphating film can be formed on the surface of the mechanical arm, so that the anti-corrosion performance and the surface hardness of the mechanical arm are improved.

Description

technical field [0001] The invention relates to the field of metal surface treatment technology, in particular to a phosphating treatment technology of a mechanical arm. Background technique [0002] Phosphating is a process in which chemical and electrochemical reactions form a phosphate chemical conversion film, and the formed phosphate conversion film is called a phosphating film. The purpose of phosphating is mainly to provide protection for the base metal and prevent the metal from being corroded to a certain extent; it is used as a primer before painting to improve the adhesion and anti-corrosion ability of the paint film layer; it can reduce friction in the metal cold processing process Use lubricated. The phosphating process has been used in industry for more than 90 years. [0003] The mechanical arm is easily corroded during long-term use. For large mechanical arms, the cost of traditional phosphating treatment is too high, and the film formation time is long, th...
