Problems solved by technology

At present, due to its low cost, steel materials still occupy a dominant position in engineering components and mechanical parts materials, but due to work needs and the influence of external environmental factors, the surfaces of components and parts are often severely worn, resulting in huge resources, Energy Consumption and Economic Loss
Using advanced surface strengthening technology to prepare a wear-resistant layer that is metallurgically bonded to the substrate on the surface of engineering components and mechanical parts is one of the effective solutions. Usually, carbon steel surface strengthening methods include carburizing / carbonitriding , surfacing, spraying, laser cladding, plasma cladding and other methods, but in these methods, the thickness of the wear-resistant layer is small, the operation is complicated, and the cost is high, which is limited in popularization and application.

Abstract

The invention discloses a method for in-situ synthesis of multiple reinforcement-phase composite coating layers by argon arc cladding, and belongs to the technical field of material surface heat treatment. Firstly, powder coating layers are precoated; then, a non-consumable electrode argon arc heat source is used for argon arc cladding of prefabricated powder and metal basal bodies; under the effect of the non-consumable electrode argon arc heat source, the alloy powder and the surfaces of the metal basal bodies are quickly molten to form molten pools; argon arc process parameters are adjusted, so that the alloy powder is reacted in the metal basal bodies in situ for synthesis of such multi-phase particle composite coating layers as TiB, TiB2 and TiN; the composite coating layers and the basal bodies are in metallurgical bonding; and reinforcement-phase particles are fine and uniformly distributed. Compared with conventional laser-clad and plasma-clad powder coating layers, argon arc cladding has the characteristics of simple process, capability of realizing manual operation and mechanical operation, low equipment cost, low powder loss and higher production efficiency.

Specifically, it is a kind of in-situ synthesis of TiB and TiB by argon arc welding. 2 , The method of TiN composite coating. Background technique [0002] Abrasion is one of the three main failure modes of materials, which causes huge economic losses. About 70% of equipment damage in industrial production is caused by various forms of abrasion. The annual loss of mechanical equipment in industrially developed countries reaches hundreds of billions According to the tribology survey report issued by the Chinese Academy of Engineering, economic losses of up to 950 billion yuan are caused by friction and wear in my country every year. Therefore, improving the wear resistance of materials plays a vital role in prolonging the service life of parts and...
