Problems solved by technology

[0005] Therefore, the market demand for composite materials with strong corrosion resistance, wear resistance and high temperature oxidation resistance is huge. In the prior art, its high temperature resistance and corrosion resistance are poor, and its service life is generally short (2-6 months), and the hammerhead wears out quickly. A large amount of iron and other elements will enter the molten aluminum, seriously affecting the quality of molten aluminum

Abstract

The invention provides a metal-based composite coating crust breaking hammer. The metal-based composite coating crust breaking hammer is prepared by the following steps: firstly, preparing high-temperature-resistant corrosion-resistant metal-based composite coating powder; secondly, making a crust breaking hammer substrate; and thirdly, performing surface cladding treatment on the crust breaking hammer substrate by adopting a plasma surfacing process, so that the high-temperature-resistant corrosion-resistant metal-based composite coating powder is molten on the surface of the substrate and issolidified quickly, and a surface coating which is metallurgically bonded with the surface of the crust breaking hammer substrate is formed on the surface of the crust breaking hammer substrate. Themetal-based composite coating crust breaking hammer overcomes the disadvantages in the prior art; the plasma surfacing process facilitates mechanization and automation, can realize large-batch stableproduction, and does not pollute the environment basically; the process is high in heating speed and high in heat efficiency; and the bonding strength of the coating and the substrate is high, and thecoating ion density is high, so that the performance and the quality of the substrate are enhanced.

Description

technical field [0001] The invention relates to the technical field of metal anti-corrosion, in particular to a shell hammer with a metal-based composite coating. Background technique [0002] With the upgrading of industrial technology, the demand for cladding products on the surface of the substrate is increasing. Whether it is the preparation of metal matrix composites and the cladding process, research is actively carried out at home and abroad. At present, commonly used cladding methods include: vacuum cladding, laser cladding, oxygen-acetylene flame cladding, high frequency cladding and other processes. Commonly used cladding materials include: self-fluxing alloy powder, carbide composite powder system, oxide ceramic powder, etc.; [0003] Metal matrix composites have properties such as corrosion resistance, oxidation resistance, and high temperature resistance, and are suitable for repairing or preparing and strengthening key equipment components to improve the servi...
