Embodiment Construction

[0014] The present invention is further illustrated below by specific examples.

[0015] Choose 4Cr13 martensitic stainless steel vernier caliper with a length of 300 mm. The equipment uses TSU-650 ultra-high vacuum magnetron sputtering and ion plating deposition equipment.

[0016] First put the 4Cr13 martensitic stainless steel vernier caliper into the acetone solution for ultrasonic cleaning for 10-20 minutes, then use absolute alcohol for ultrasonic cleaning for 10-20 minutes, and finally dry it with a hair dryer; fix the surface-clean caliper on the TSU-650 ultrasonic On the workpiece frame in the high-vacuum magnetron sputtering and ion plating deposition equipment, the workpiece frame can rotate while revolving. After installation, close the chamber door and wipe the sealing ring with absolute alcohol to ensure that there are no impurities on it. Turn on the vacuum system to start vacuuming. When the vacuum reaches a certain degree, turn on the heating system and heat...

Abstract

The invention discloses a technology for depositing a titanium nitride film on the surface of a 4Cr13 stainless steel vernier caliper. The technology comprises the steps of cleaning the surface of the 4Cr13 stainless steel vernier caliper in a physical way and a chemical way; then, depositing pure metal or an alloy with the thickness of 0.1-0.5 micron on the surface of the 4Cr13 martensitic stainless steel vernier caliper as a transition layer by an arc ion plating, ion sputtering plating or radio frequency (RF) sputtering plating technology, wherein the transition layer can be made of pure titanium, pure nickel, pure copper, pure molybdenum, pure chromium or the like, and the alloy can be an iron-carbon alloy, a tungsten-molybdenum alloy, a nickel-chromium alloy or the like; and filling reactant gases including nitrogen and argon in a certain ratio to obtain the hard titanium nitride film with the deposition thickness of 0.5-1 micron. The titanium nitride film deposited on the surface of a tool such as the vernier caliper is high in strength and hardness, and has corrosion-resistant and wear-resistant properties and a good visual effect.

Description

technical field [0001] The invention belongs to the technical field of surface engineering, in particular to a process for depositing a titanium nitride film on the surface of a 4Cr13 stainless steel vernier caliper. Background technique [0002] The vernier caliper has the characteristics of simple structure, convenient use, high precision and wide range of the measured workpiece size. It is a widely used measuring tool in industry. Its material is generally mainly martensitic stainless steel. This type of steel has the advantages of high strength, small deformation and good hardenability, but its corrosion resistance, surface quality and wear resistance are relatively poor. The invention deposits a titanium nitride hard film layer on the surface to improve the surface performance and obtain better practicability. Contents of the invention [0003] The purpose of the present invention is to provide a process for depositing a titanium nitride film on the surface of a 4Cr...
