Between 300℃-450℃. The temperature of titanium plating by ion evaporation depends on the material and purpose of titanium plating. The material and purpose of titanium plating by ion evaporation are also one of the factors for temperature control. Ion evaporation is a chemical surface treatment technology performed under vacuum conditions. By coating the material surface with specific elements at high temperatures, it can not only improve the hardness, wear resistance and chemical stability of the object, but also improve the electronics and optical performance. Ion evaporation is generally divided into gold plating, silver plating, titanium plating, etc., and titanium plating is one of the most common and important applications. Ion evaporation titanium plating is used for surface treatment of metal materials, such as steel, copper, and aluminum. etc., can be used to improve the properties of materials, such as improving hardness, corrosion resistance, wear resistance, etc. Ion evaporation titanium plating can also be used in high-tech fields such as electronic components, aerospace equipment, medical equipment, and watches.
