Abstract： |
The present invention relates to mechanical engineering surface treatment technology. The invented method is as follows: prepare phosphoric acid and aluminium hydroxide aqueous solution, prepare phosphoric acid and sodium silicate, aqueous solution, take treated diaspore, ceramic and solid micro granules of other material to mix with fore said two solutions proportioning to form paint, which is coated or sprayed on aluminium alloy surface, heat treatment under 200 deg.C temp.. Repeat the fore said coating and heat treatment to form coating layer on substrate body surface. The advantages include low treatment temp., relation simple in technological condition, low cost, no pollution, abrasive resistance, corrusion resistant, heat resist etc. |
