Abstract

The invention discloses a titanium-aluminum-silicon-tantalum alloy material and a preparation method thereof. The titanium-aluminum-silicon-tantalum alloy material is prepared from the following components by atomic percent: 1 to 97 percent of titanium, 1 to 97 percent of aluminum, 1 to 50 percent of silicon and 1 to 30 percent of tantalum. The titanium-aluminum-silicon-tantalum alloy material is prepared by a cold spraying method. The cold spraying method comprises the following steps of firstly, mechanically mixing raw materials (titanium powder, aluminum powder, silicon powder and tantalum powder); secondly, performing pretreatment such as rust removal, oil removal, sand blasting, cleaning and drying on the surface of a matrix; and finally, performing cold spraying in the protective atmosphere (inert gas such as helium and nitrogen or mixed gas of helium and nitrogen) to prepare the titanium-aluminum-silicon-tantalum alloy material. The titanium-aluminum-silicon-tantalum alloy material disclosed by the invention has the advantages of high density, no segregation, uniform structure, fine grains, unlimited size and the like.

Description

technical field [0001] The invention relates to the technical field of titanium alloy and its preparation process, in particular to a titanium-aluminum-silicon-tantalum alloy material and a preparation method thereof. Background technique [0002] Surface engineering is to change the surface morphology, chemical composition, tissue structure and stress state of solid metal or nonmetal through surface pretreatment, surface coating, surface modification or multiple surface technology composite treatment to obtain the required surface properties. systems engineering. Depositing one or more layers of thin films with completely different properties on the surface of materials has become one of the effective ways to improve the properties of matrix materials. The target material in the coating material is a key factor affecting the quality of the film. With the development of thin film technology, coating materials are constantly updated. [0003] Titanium nitride is the most m...
