AI Technical Summary

Technical Problem

In the existing alloy tool coating deposition process, the problem of uneven coating results in some areas having excessively thin coatings or peeling off, affecting the tool's wear resistance and service life.

Method used

The coating solution is uniformly deposited on the tool surface by using inner and outer ring coating nozzles combined with high-pressure nitrogen gas jet, along with a rotating shaft and heating element. High-pressure nitrogen gas is used to remove excess droplets, improving the uniformity and density of the coating and preventing coating cracking.

Benefits of technology

It achieves uniform coating deposition, improves coating adhesion and wear resistance, enhances tool life and coating quality, and is suitable for coating requirements of various alloy tools.
