Abstract

PURPOSE:To impart excellent wear-resistance and lubricating characteristics to the surface of an Al-material, by heating the Al-material, to which hard alumite treatment is preliminarily applied, to generate a large number of cracks to the alumite film thereof, an impregnating the alumite film with a lubricant comprising a fluorine type or silicon type resin to secure the same. CONSTITUTION:An Al-material is subjected to hard alumite treatment to form an alumite film to the surface thereof. This Al-material is heated to 200-300 deg.C to generate a large number of cracks to the alumite film. In the next step, the alumite film having a large number of cracks formed thereto is impregnated with a lubricant comprising a fluorine type or silicon type resin excellent in lubricating characteristics to secure the same to the cracked parts.

The aluminum material is first treated with hard alumite 1 (hard anodic oxidation treatment) according to known conditions to form a microscopically porous hard alumite film (hard @divine anodization film) on its surface. . The coating itself has a high hardness of 300 or more in Vickers hardness, for example, and has excellent wear resistance.

Therefore, next, the aluminum material subjected to the hard alumite treatment is heat treated at a predetermined temperature to create many cracks in the film of the hard alumite 1. This heating temperature is
It is selected appropriately depending on the use of the aluminum material, but in order to prevent many cracks from remaining in the form of grooves even after cooling, the temperature is usually about 200 to 250°C, particularly preferably 230°C. It is preferable to heat it to about .degree.

Therefore, next we will examine the aluminium 1 that has formed these many cracks.
- The film is impregnated with a lubricant made of a fluororesin or silicone resin with excellent lubrication properties, and this is fixed in the holes or grooves of the hard alumite film including the cracked parts. This impregnation and fixation is done in advance with aluminium 1.
By applying a dispersion or solution of the lubricant by rubbing it onto the surface of the hard alumite film in a state where ~ has been cooled to, for example, -20°C, and then wiping off the excess lubricant after returning it to room temperature ( It is advantageous to cool the aluminum material, impregnate it with the lubricant, and then return it to room temperature and perform a post-heat treatment of 7 m-1, so that the lubricant is applied to the aluminum film. Due to its relatively small coefficient of thermal expansion, it can be tightly fixed and covered in a comb.
