Abstract

The invention discloses a stainless steel surface treatment method and a stainless steel watch shell. The stainless steel surface treatment method includes the following steps that S1, pretreatment is conducted on a stainless steel workpiece; S2, the stainless steel workpiece is put into a plating assistant agent, and plating assistant treatment is conducted through ultrasonic oscillation; S3, the stainless steel workpiece is put into hot-dip aluminum plating liquid, and hot-dip plating and aluminizing treatment is conducted through ultrasonic oscillation; S4, the stainless steel workpiece is put into oxidization electrolyte, and hard anodizing treatment is conducted through ultrasonic oscillation; S5, color coated treatment is conducted on the stainless steel workpiece; and S6, the stainless steel workpiece is put into hole sealing treatment liquid, hole sealing treatment is conducted through ultrasonic oscillation, and then the stainless steel workpiece is dried. By means of the stainless steel surface treatment method, the defects that by means of an existing ion plating method, the bonding force of an aluminum plating layer and a stainless steel base body is poor, and if base transition layer film coating is adopted, the process cost is increased, and high process cost caused by the fact that time is seriously consumed due to ion plating of thick films are overcome.

Description

technical field [0001] The invention relates to chemical surface treatment of metal materials, in particular to a surface treatment method for stainless steel and a stainless steel watch case made by the surface treatment method. Background technique [0002] Stainless steel materials have superior corrosion resistance, wear resistance, toughness and process performance (corrosion resistance, not easy to oxidize, etc.), so they are widely used in aerospace, ocean, energy, construction, chemical industry, food machinery, electromechanical industry, household appliances and other industries. With the continuous development of social economy and the gradual improvement of living standards, people urgently require high-grade color and diversified decoration of stainless steel materials. Therefore, stainless steel surface treatment technology has been widely concerned. Since the International Nickel Corporation (INCO) announced in 1972 that it had developed the world's first co...
