advanced ceramic tool

Several new ceramic tools that are currently being developed but have broad application prospects include gradient ceramic tools and ceramic hard tools

Alloy composite blade and powder coated ceramic tool.

(1) The functionally gradient ceramic tool refers to the ceramic with reasonable gradient changes in composition, structure and physical and mechanical properties

Tools. By designing the gradient structure layer reasonably, the tool surface has the maximum thermal conductivity, which is beneficial for reducing the tool

The temperature gradient and thermal stress gradient inside to improve the ability to resist thermal wear and damage; Simultaneously make the surface of the cutting tool

There is a minimum linear expansion rate, so compressive stress is formed on the surface during tool preparation to counteract the cutting process

The tensile stress generated can improve the tool's resistance to mechanical stress damage.

(2) Ceramic hard alloy composite blade refers to a new type of blade obtained by combining ceramics and hard alloy through sintering method

With. The surface layer of the composite blade is made of ceramic material, and the lower or middle layer is made of hard alloy. The thickness of surface ceramics is higher than that of ordinary hard alloy coatings

The layer needs to be large and can withstand greater bending loads compared to ordinary ceramics.

(3) Powder surface coating ceramic tool refers to coating ceramic on the surface of cemented carbide powder to make composite powder, and then heating the composite powder

A new type of tool made by pressing. Powder coated ceramic tools break through the traditional method of coating on the tool surface, changing the macro coating to

Micro coatings overcome the drawbacks of macroscopic coatings such as easy peeling and chipping.
