Problems solved by technology
However, the bonding force between metal and plastic is limited, there is a risk of detachment between the two, and it is difficult to improve the composite reliability
[0004] On the other hand, in order to make the plastic injection molded and fixed on the metal, it is often necessary to chemically treat the metal. The materials used in the chemical treatment are harmful to the human body, pollute the environment, and the cost is relatively high.

Abstract
The invention discloses a stainless steel and plastic combined part and a machining method thereof. The stainless steel and plastic combined part comprises a stainless steel substrate. Honeycomb thin holes are formed in the surface of the stainless steel substrate, and an oxidation film is formed on the surfaces of the honeycomb thin holes through passivating treatment of an organic oxidizing solution. The oxidation film at least comprises two of ferric oxide, chromium oxide and nickel oxide. A plastic material is arranged on the stainless steel substrate in an injection moulding manner and is embedded in the honeycomb thin holes. According to one technical effect of the stainless steel and plastic combined part, the oxidation film has a good heat insulation effect, and the combination acting force between the stainless steel substrate and the plastic material is improved.
Description
technical field [0001] The invention relates to the technical field of material processing, in particular to a combination piece of stainless steel and plastic and a processing method thereof. Background technique [0002] With the gradual development of material technology, more and more products adopt the form of metal and plastic composite to form the product structure. This structural design can achieve rich functional effects. For example, when the appearance of the product needs to show metal features and the internal structure needs to reduce weight and save material costs, a metal and plastic composite design can be used. [0003] The traditional composite methods of metal and plastic include adhesive bonding, snap fit or rivet connection. However, the traditional composite method has defects such as low composite reliability and the need to increase fixed connection mechanisms. With the development of technology, there has also been a composite method of injectin...
