Abstract

The invention provides a manufacturing method of an aluminum rotary target material. The method comprises S1, aluminum powder with the average grain diameter D50 of 10-80 micron is manufactured; S2, astainless steel tube or a titanium tube is taken as a target material base tube, and surface sand blasting treatment is conducted on the target material base tube; S3, cold spraying and forming are conducted, the manufactured aluminum powder is loaded into a cold spraying powder feeder, the processed target material base tube is installed on a transmission device to enable the target material base tube to rotate, a cold spraying gun and the target material base tube do relative motion in the horizontal direction to prepare the target material; and S4, the sprayed target material is machined into that with required size and precision, and a finished product is prepared. According to the method, the manufacturing process of the aluminum rotary target material is simple, the density of the manufactured aluminum rotary target material is far higher than that of a traditional thermal spraying technology, the relative density can reach 95-99%, the oxygen content is lower than that of the traditional thermal spraying technology, grain tissues are uniformly refined, the yield is high, the powder utilization rate is high and large-scale production is facilitated.

Description

technical field [0001] The invention relates to a rotating target material, in particular to an aluminum rotating target material, and also relates to a manufacturing method of the aluminum rotating target material. Background technique [0002] Due to the rapid development of optical glass, touch screen and other industries, the demand for aluminum rotating targets is increasing, and the quality requirements for aluminum rotating targets are also getting higher and higher. The utilization rate of existing aluminum targets in the coating process is not high, resulting in high production costs for rotating targets. Contents of the invention [0003] In view of this, the object of the present invention is to provide an aluminum rotary target and a manufacturing method thereof. The quality of the aluminum rotary target produced by the method is good, the utilization rate of the target in the coating process is high, and the production cost of the rotary target is greatly red...
