Abstract

The invention belongs to the technical field of watch related parts, and particularly relates to a gold-plated 316 stainless steel watch band. According to the gold-plated 316 stainless steel watch band, 316 stainless steel is adopted as a base material of the watch band, and due to adding of a molybdenum element in the 316 stainless steel, the 316 stainless steel itself has good corrosion resistance, abrasion resistance, high temperature resistant characteristics and high mechanical strength; in the gold-plated 316 stainless steel watch band, the surface of the 316 stainless steel base material comprises a hard gold layer, a main gold layer and a surface gold layer; due to the fact that the surface gold layer is K gold, different colors can appear; and on the basis that the ornamental value of the watch band is improved, the hard gold layer, the main gold layer and the surface gold layer guarantee the abrasion resistance and the corrosion resistance of the watch band at the same time,and the binding force between a gold-plated layer and the base material is high.

Description

technical field [0001] The invention belongs to the technical field of watch-related components, and in particular relates to a gold-plated 316 stainless steel watch band. Background technique [0002] Watch strap is a general term for the effective part of the watch to fix the wrist. Watch straps come in a variety of materials, the two most important of which are leather and metal. The more precious metal watches are made of platinum, K gold, semi-gold, gold-clad, gold-plated and silver. Other metal materials mainly include copper, titanium, tungsten-titanium alloy and other materials. However, platinum, gold and other precious metals with better corrosion resistance are often rare and expensive. However, the corrosion resistance of different metal materials such as copper, titanium, and tungsten-titanium alloys is often not satisfactory. Stainless steel materials have superior corrosion resistance, wear resistance and toughness, and are a good choice for watch strap mate...
