Abstract
The invention belongs to the technical field of automobile spraying and particularly provides a novel automobile electric arc spraying method. A spraying base material is pretreated and preheated; then, the base material is sprayed; spraying process parameters are as follows: spraying voltage is 25-35V, spraying pressure is 0.50-0.60MPa, and a spraying distance is 150-220mm; after result analysis, optimum parameters are obtained as follows: the spraying voltage is 30V, the spraying pressure is 0.60MPa, and the spraying distance is 200mm; through metallurgical structure observation, an obtained coating is uniform and dense, has few oxide impurities, small porosity and good wear resistance.
Description
Technical field
The invention belongs to vehicle spray painting technical field, especially a kind of method of automobile electric arc spraying.
Background technology
Spraying refers to the process that pigment or coating is acted on to workpiece surface.In modern manufacturing industry, spraying process is very important link in products production, except outward appearance, the more important thing is the direct performance such as anticorrosion, antirust that affects product, and it is widely used in the fields such as five metals, automobile, boats and ships, military project.Conventional spray paint method has the impact spraying quality of production and a series of shortcomings such as production efficiency is low, especially very large on workers ' health impact.
Arc spraying technology can be according to different spraying equipments, spray material, and body material comes, and regulates spray voltage, spray pressure, spray distance, waits spraying parameter, makes the processing parameter of spraying reach best; Thereby make substrate material surface there is the performances such as wear-resisting, anti-corrosion, anti-oxidant.Production efficiency is high, and coating quality is high, and energy consumption and cost are low.
Summary of the invention
For Shortcomings in prior art, the invention provides a kind of automobile electric arc spraying process of simple, high-quality, can effectively improve coating interface bonding strength, thereby significantly improve, matrix is corrosion-resistant, high temperature wear resistant performance.
The present invention realizes above-mentioned technical purpose by following technique means.
The present invention adopts 400 type arc-spraying machines, and spray material is: homemade FeNiAl spray coating alloy material; Body material is Q255 structural carbon steel, size 100mm × 50mm × 5mm;
Concrete steps are as follows:
(1) pre-treatment before spraying: before spraying, gasoline for substrate material surface or acetone solvent are cleaned, to be dried after, then use emery cloth roughening treatment;
(2) preheating: by modes such as heating by electric cookers, body material is carried out to preheating, preheating temperature is at 80-130 DEG C;
(3) spraying: preheating body material is later sprayed: spraying parameter is: spray voltage is 25-35V, and spray pressure is 0.50-0.60MPa, and spray distance is 150-220mm.
The invention has the beneficial effects as follows:
(1) spraying base material is restricted hardly, can make metallic substance, stupalith, amorphous material, timber, cloth, paper etc.;
(2) in spraying process, body material heating temperature is low, and structure property changes very little, is out of shape little.
