CUTTING TOOL - A simplified explanation of the abstract

This abstract first appeared for US patent application 18279600 titled 'CUTTING TOOL

The cutting tool described in the patent application consists of a base material with a coating that includes a hard particle layer made up of titanium, silicon, carbon, and nitrogen. The concentration of silicon within the hard particles changes periodically along a specific direction, and the orientation of the hard particle layer is in a specific orientation.

• The coating of the cutting tool contains a hard particle layer composed of titanium, silicon, carbon, and nitrogen.
• The concentration of silicon within the hard particles changes periodically along a specific direction.
• The orientation of the hard particle layer is in a specific (422) orientation.

Potential Applications: This technology could be used in various cutting applications, such as in the manufacturing industry for precision cutting of materials like metal or ceramics.

Problems Solved: The cutting tool with this specific coating can provide enhanced durability and cutting performance, making it suitable for demanding cutting tasks.

Benefits: The cutting tool's coating with a hard particle layer offers improved wear resistance and cutting efficiency, leading to longer tool life and better cutting results.

Commercial Applications: This innovative cutting tool technology could have significant commercial applications in industries that require high-precision cutting tools, such as aerospace, automotive, and medical device manufacturing.

Questions about the technology: 1. How does the periodic change in silicon concentration within the hard particles affect the cutting performance of the tool? 2. What specific advantages does the (422) orientation of the hard particle layer provide in terms of cutting efficiency and tool longevity?

Original Abstract Submitted

A cutting tool comprising a base material and a coating disposed on the base material, wherein the coating comprises a hard particle layer, the hard particle layer is formed from a plurality of hard particles including titanium, silicon, carbon, and nitrogen; in the hard particles, a concentration of the silicon periodically changes along a first direction set in the hard particles; and an orientation of the hard particle layer is a (422) orientation.
