[0002] Titanium aluminum nitride coating refers to a thin film composed of titanium nitrogen compounds. Titanium nitride is an interstitial compound with a beautiful golden luster, good chemical stability, a melting point of up to 3000°C, and a Vickers microhardness of about 20GPa.

[0003] Before the existing titanium aluminum nitride coating is completed in the last process, its surface needs to be sandblasted and polished because slight scratches and oxidation may appear on its surface during processing. However, most of the existing sandblasting devices are handheld for sandblasting. Handheld sandblasting will cause a certain degree of fatigue to workers due to long working hours. During the sandblasting process, since the workers manually control the metal castings, the positions of the metal castings are not fixed. During sandblasting, some positions may be far from the spray gun, while some positions are close, resulting in uneven sandblasting effect. Therefore, an oxide layer sandblasting device for titanium carbide nitride coating is proposed to solve the above problems. Utility Model Content
