The position of~15mm is at the uniform velocity moved relative to automobile parts sprays oxygen plasma beam to automobile parts surface, to automobile parts table
Face carries out vacuum plasma treatment, and the spray gun is 50~100mm/s with respect to the movement speed of automobile parts；
(4) gas nitriding: 100~150 DEG C of 1~2h of heat preservation are passed through ammonia, and 300~400 DEG C are heated and keep the temperature 2~4h；
(5) plated films: under the conditions of 100~150 DEG C of temperature, even application nano aluminium oxide forms nano aluminium oxide
Film；
(6) secondary film coating: at 50~80 DEG C of temperature and 10~20% damp conditions, even application mass ratio is 1: (0.1
~0.3) mixture of nano silica and flyash forms nanometer titanium dioxide silicon thin film；
(7) glaze is sprayed: the automobile parts surface after glaze atomization to be sprayed onto secondary film coating, 120~150 DEG C of drying, water
It washes, forms glaze layer；
(8) plated film three times: fluorine element high molecula resin film is plated in glaze layer surface using physical vaporous deposition, i.e. completion automobile
The surface treatment of accessory.
It is 1 that chemical polishing reagent, which is the ratio between amount of substance, in the step (1): the nitric acid and glacial acetic acid of (0.5~1)
Mixed liquor.
