Weld line phenomenon prevents phenomena such as affixing the lines of the hand, product scratch, breaking, and color unifies no color differnece, and smooth surface is beautiful,
Enhance titanium article case hardness, improve its overall performance.
The used in order to achieve the above objectives technical solution of the present invention is：
A kind of surface treatment method for the fission of titanium article titanium molecule, which is characterized in that include the following steps：
(1) titanium article is polished and degreased；
(2) it puts the titanium article after polishing into vacuum heat stove, and keeps negative pressure 8-10Pa；
(3) temperature in vacuum heat stove is warming up to 1000-1500 DEG C, and constant temperature 1-5h；Again from high temperature 1000-
1500 DEG C are down to 100-500 DEG C, and add in air, then constant temperature 0.5-4h, blow-on.
As a further improvement on the present invention, it is further comprising the steps of：
(4) liquid gas is passed through to cool down titanium article.
As a further improvement on the present invention, the liquid gas is liquid nitrogen.
As a further improvement on the present invention, in the step (3), the time required to temperature is warming up to 1000-1500 DEG C
For 1-4h.
As a further improvement on the present invention, in the step (3), temperature is down to 100-500 DEG C from 1000-1500 DEG C
Required time is 20-60min.
Beneficial effects of the present invention are：Using novel process of surface treatment, by being surface-treated to titanium article, titanium
Impurity after high temperature by being disposed of in product, and meet the requirement of environmental protection is safe to use；Meanwhile after processing without polishing line with
Weld line phenomenon prevents phenomena such as affixing the lines of the hand, product scratch, breaking, and color unifies no color differnece, and smooth surface is beautiful,
Enhance titanium article case hardness, improve its overall performance.
Above-mentioned is the general introduction of inventive technique scheme, and below in conjunction with specific embodiment, the present invention will be further described.
