Abstract

The invention discloses a preparation method for high-purity nanoscale titanium-nickel alloy powder. The method is implemented in a high-temperature evaporation chamber, a cooling pipe and a collector which are communicated in sequence. Added nickel raw materials and titanium raw materials are evaporated into mixed steam through the high-temperature evaporation chamber, the mixed steam is cooled into fine particles through the cooling pipe in a water cooling mode, the fine particles are filtered through a filter screen with fine filtration pores and enter the collector, and finally the high-purity nanoscale titanium-nickel alloy powder is obtained after drying. In this way, the content of oxygen in the prepared titanium-nickel alloy powder can be lowered, the purity of titanium and nickel is substantially improved, and the alloy powder has the consistent particle size.

Description

technical field [0001] The invention relates to a preparation method, in particular to a preparation method of high-purity nano-scale titanium-nickel alloy powder. Background technique [0002] With the continuous development of science and technology, the development of the current production and processing industry is mainly focused on the production of nano-scale materials. However, in the production of titanium-nickel alloy powder, due to unsuitable equipment or unreasonable adjustment of process parameters, etc. , often makes the titanium-nickel alloy powder produced have irregular particle shape, high internal oxygen content, poor purity, and particle size does not meet the requirements, which affects the titanium-nickel products made of the titanium-nickel alloy powder performance. Contents of the invention [0003] The technical problem mainly solved by the invention is to provide a preparation method of high-purity nano-scale titanium-nickel alloy powder. [000...
