Embodiment Construction

[0017] 1. The present invention provides the multiple alloy co-infiltration surface treatment technology of the container workpiece, and the specific process steps are as follows:

[0018] (1) Zinc powder 15~30%, aluminum powder 0~20%, nickel powder (nickel salt powder) 0~2%, rare earth powder 0~2%, NH 4 Cl ammonium chloride 0~4%, the balance is filler (Al 2 o 3 and SiO 2 ) powders are evenly mixed to obtain multiple osmotic agents;

[0019] (2) Pre-treatment of the workpiece for degreasing and derusting;

[0020] (3) Heat the well-mixed multi-component permeation agent and the pre-treated workpiece to 400°C in a closed container, keep the temperature at 250-400°C for 1-6 hours, and carry out multi-component alloy co-infiltration to form a 15-120㎛ Multi-element alloy co-infiltration layer;

[0021] (4) After the workpiece comes out of the furnace and cools for 1~6h, separate the workpiece from the multi-component penetrating agent, and clean the surface of the workpiece; ...

Abstract

The invention discloses a multi-component alloy co-permeation surface treatment process for a container workpiece. The process specifically comprises the steps of uniformly mixing a multi-osmotic agent such as zinc powder, nickel powder and aluminum powder; pre-treating the workpiece with degreasing and derusting; heating the multi-osmotic agent and the pre-treated workpiece to 400 DEG C in a closed container and kept at a temperature of 250-400 DEG C for 1-6 h; after the workpiece is discharged and cooled for 1-6 h, separating the workpiece from the multi-osmotic agent to remove the surface of the workpiece; and post-treating the workpiece by polishing, passivation, phosphating, coating, etc., specifically, color of the outer surface coating of the multi-component co-permeation alloy layer can be arbitrarily selected. The multi-component alloy co-permeation surface treatment process for the container workpiece has good corrosion resistance, wear resistance, scratch resistance, thermalstability and adhesion, uniform permeation layer, no hydrogen embrittlement phenomenon, compatibility with other coating systems, low cost, no waste discharge, no pollution to the environment, and the like.

Description

technical field [0001] The invention relates to a multi-element alloy co-infiltration surface treatment technology for container workpieces, in particular to an anti-corrosion and wear-resistant technology for container workpieces. Background technique [0002] Container door locks, door hinges and other parts require high corrosion resistance and wear resistance. At present, the anti-corrosion and wear resistance treatment of these parts mainly uses hot-dip galvanizing process, which is polluted Environmental, high cost, poor corrosion resistance, poor wear resistance and other disadvantages. Contents of the invention [0003] In order to overcome the deficiencies in the prior art, the present invention provides a multi-element alloy co-infiltration surface treatment technology for container workpieces. The specific process steps are as follows: [0004] (1) Zinc powder 15~30%, aluminum powder 0~20%, nickel powder (nickel salt powder) 0~2%, rare earth powder 0~2%, NH 4 ...
