Abstract
The invention discloses a coating method of dry film lubricant coatings of titanium and titanium alloy wire rods. The coating method comprises the following steps: firstly roughening the surfaces of titanium and titanium alloy wire rod blanks by using a planetary polishing machine, using a vertical bending mechanism for sizing the rolling diameter of the wire rods and providing active force, then feeding the wire rods into a coating liquid box, so that coating is uniformly adhered to the surfaces of the wire rods, naturally homogenizing the coating under the action of gravity to form films, further carrying out surface dry on the coatings through induction heating, and finally carrying out low temperature heat treatment to obtain the titanium and titanium alloy wire rods with the dry film lubricant coatings. The coating method has the beneficial effects that the coating adhered to the surfaces of the titanium and titanium alloy wire rods uniformly forms the films, the production efficiency can be improved by using induction heating for carrying out surface dry on the liquid films, and the device space is saved; the coating scratching caused by follow-up bending and sizing and other processing does not occur; the surfaces of the dry film lubricant coatings are uniform; and the coating method is simple in operation, easy to realize and suitable for large-scale commercial process.
