Hardware workpiece surface treatment technology

Abstract

The invention discloses ahardware workpiece surface treatment technology. The hardware workpiece surface treatment technology comprises the following steps thata base material pre-treated, specifically, a hardware workpiece is subjected to ultrasonic cleaning to remove impurities on the surface, and thehardware workpiece is dried; the base material ground, specifically, a physical method is used for grinding the surface of the hardware workpiece to uniformly roughen the surface of the hardware workpiece; silanization treatment is carried out, specifically, the uniformly roughened hardware workpiece is placed into an organosilane aqueous solution for silanization treatment, so that a silane film is formed on the surface of the hardware workpiece; middlecoating treatment is carried out, specifically, the surface of the silane film is subjected to UV coating spraying to form a UV coat on the surface of the silane film; and outeroverlaying layer treatment is carried out, specifically, thesurface of the UV coat is subjected to TD treatment to form a metal carbide layer on the surface of the UV coat. According to the hardware workpiece surface treatment technology, protection overlay layers with extreme high binding force are formed on the surface of the hardware workpiece, and the overlay layers are not liable to fall off from the surface of the hardware workpiece, so that the hardware workpiece can be protected for a long time; and the overlay layers have excellent performance of corrosion resistance and abrasion resistance.

Description

technical field [0001] The invention relates to a surface treatment process of a hardware workpiece. Background technique [0002] With the continuous development of science and technology, the hardware industry is also constantly rising. Hardware workpieces play an important role as supporting products, semi-finished products and tools used in the production process of industrial manufacturing, and hardware workpieces are cheap and have good practical value. It is indispensable in daily life and industry, and is widely used. However, most hardware workpieces have many problems during use, such as: easy to be corroded, problems caused by wear, and bonding. In view of the above defects, the prior art usually It is protected by copper plating, but the wear resistance and other properties of the copper layer cannot meet the industrial requirements for the wear resistance of the workpiece, and the combination of the copper layer and the workpiece is not reliable, which makes the...
