Embodiment Construction

[0028] Illustrated by the following exemplifications, but these exemplifications are not in any way limiting of the process of the invention.

[0029] Example 1 The material of the test plate is selected from carbon steel, high-low alloy steel or stainless steel respectively, the specification is 50mm×50mm×3mm, polished to the surface roughness Ra1.6~Ra0.8, and set aside. ①The sample is degreased with alkaline degreasing solution at 60-75°C for 5-10 minutes; rinsed with tap water for 30 s, rinsed with running water for 15 s; then acid-washed and activated in 10% sulfuric acid solution at room temperature for 2-10 min; rinsed with tap water for 30 s, rinsed with running water for 30 s; For high-alloy steel and stainless steel, the process method given in Table 1 should be used for electrolytic activation to remove the passivation film on the surface, and a thin nickel layer should be pre-plated with flash nickel plating.

Abstract

The iron and steel material treating process with synergistic fluoropolymer coating features the first chemical nickel plating of iron and steel material to form the base layer of the synergistic coating, the subsequent pore creating treatment of the nickel coating, the introducing of fluoropolymer to the pores and surface and the heat treatment under vacuum state for the fluoropolymer to fuse with the chemical coating to form the synergistic coating. The said technological process has the advantages of high coating hardness, high wear resistance, the self-lubricating performance and increased wear resistance caused by the fluoropolymer as friction reducing matter, resistance to most harmful matters of the fluoropolymer, and self-lubricating function of the dry coating.

Description

technical field [0001] The invention relates to steel coating treatment, in particular to a steel fluorine-containing polymer synergistic coating treatment process. Background technique [0002] Metal surface synergistic modified coating technology is a new type of surface composite modified coating technology. In the study of improving the coating layer and surface treatment performance of metals, researchers have successfully used the combination of two or more materials and The advantages of the process to obtain the desired material performance characteristics; such as light metal anodized film combined with low-friction polymers or lubricants to control penetration, and then modified by precision treatment, and finally a precision overall coating and It has become an integral part of metal parts. This kind of coating is a synergistic coating. Its comprehensive performance exceeds that of composite coatings in the general sense, and it has great application value. The m...
