The weight percentage for the components of the hyaline coating is as follows: SiO2 45 to 54 percent, B2O3 15 to 20 percent, one or more of Na2O, K2O and Li2O, 10 to 24 percent, one or more of TiO2, ZrO2 and ZnO, 6 to 18 percent , and the rest is one or more of CaO, MgO and CeO2. Firstly, the glass powder is mixed with the mill additions to be pulped and then plated on the surface of titanium or the titanium alloy. After being dried, the surface of titanium or the titanium alloy is directly used for a thermal hydrogen treatment or smelted at a temperature of 900 to 1, 000 DEG C for 15 to 30 minutes and then a hyaline coating with a thickness of 20 to 70 micrometers is formed on the surface of titanium or the titanium alloy; secondly, titanium or the titanium alloy plated with the coating is conducted a thermal hydrogen treatment. After the treatment technique is finished, the coating flakes off automatically in the process of cooling; and finally, a surface treatment is supplemented to meet the requirement of the workpiece surface.
