Abstract

The invention discloses a processing technology for enhancing thermal protection of a metal piece. The processing technology comprises the following steps of preparation of an interfacial agent: adding 50-70 parts of acrylamide into a magnetic stirrer, then adding 3, 5-diamino-1, 2, 4-triazole accounting for 20-30% of the total amount of acrylamide, raising the reaction temperature to 95-105 DEG C, and reacting for 20-30 minutes. According to the invention, the metal piece is subjected to irradiation treatment in the cold plasma box firstly and then is irradiated with 60CO-gamma rays, so that the surface of the metal piece is fully activated, the infiltration capacity of a surface microstructure of the metal piece is improved, an interfacial agent is composed of acrylamide, 3, 5-diamino-1, 2, 4-triazole and other raw materials, and after the interfacial agent and the metal piece are subjected to microwave activation, various active groups are grafted on the surface.

Description

technical field [0001] The invention relates to the technical field of metal protection, in particular to a processing technology for enhancing the thermal protection of metal parts. Background technique [0002] The metal heat protection layer plays an important role in increasing the working temperature of the material, the service limit of the material, and broadening the application range of the material. Since the heat protection layer has the characteristics of good high-temperature chemical stability, erosion resistance and heat insulation, and can reduce the service temperature of the metal substrate, it can cause a large temperature drop between the high-temperature gas and the metal parts of the working substrate, thereby It has many advantages such as protecting the substrate from high-temperature oxidation, and achieves the purpose of prolonging the life of parts of the heat engine and improving the thermal efficiency of the heat engine. It is one of the most adv...
