Problems solved by technology

However, after actual use, it is found that: ABS base plastic products are not resistant to sulfuric acid corrosion, and will be crushed and broken when encountering sulfuric acid, and ABS plastics cannot withstand high temperatures, and have poor affinity for ceramic coatings. Therefore, the high-hardness ceramic coating has become an urgent problem to be solved.

Abstract

The invention discloses a method for preparing a nano-ceramic coating interface on the surface of an ABS product. The method comprises the following steps: carrying out surface degreasing, surface hydrophilic treatment, surface roughening treatment, surface neutralizing treatment, pre-impregnating treatment, palladium immersion, peptizing, alkaline nickel plating, cleaning, drying, gas plasma cleaning pre-treatment and metal plasma high-energy injection pre-treatment; and after metal ion high-energy pre-treatment is completed, gradually and slowly reducing ion energy, and continuously and slowly charging a reaction gas until an interface blend layer continuously transiting to ceramic from metal is formed. According to the method disclosed by the invention, the surface of the ABS product is treated by virtue of the advantages of a metal plasma source, the defect of no high-temperature resistance of ABS plastic is overcome with the adoption of the method of alkaline low-temperature nickel plating, and then metal epitaxial growth and film coating, and metal film surface ceramization are carried out to complete preparation for a high-hardness ceramic coating with a high binding force on the ABS product; and meanwhile, the appearance needs of smoothness and the like of the surface ceramic coating can be met.

Description

technical field [0001] The invention relates to a method for preparing a nano ceramic coating interface on the surface of an ABS product. Background technique [0002] With the development of society, ceramics occupy an important position in many fields and are recognized by many consumers. The use environment of ceramics is very complicated, especially in high temperature environments, which greatly reduces the service life and increases costs. Therefore, the traditional Advanced ceramic materials can no longer meet the increasingly demanding work requirements, and the development of new composite materials with high temperature resistance, corrosion resistance, impact resistance, fatigue resistance and wear resistance has become an important topic in material science research. [0003] Currently, vacuum-based deposition techniques are commonly used to form thin layers of conductive coatings or ceramic materials. For example, thin layers of transparent materials such as in...
