Metallurgical technology of metal ceramics

1. What are the difficulties in the production of cermets?
The production difficulty of cermet mainly lies in the precise control of its components. The C/N ratio of cermets is not easy to control, which affects the performance of the products. Domestic manufacturers can not better grasp the composition of cermet material, to make the product stability is not good.
 
2. How many factors affect the use effect of cermet products?
The influence factors of the use effect of cermet products are reflected in the following aspects:
1) The material itself is not good enough (but luxury materials do not have this problem);
2) the product shape can not meet the requirements (even if it can be used, the effect will be reduced, such as the clamping geometry size can not meet the requirements);
3) Processing defects (due to the improper force of the product in the process of processing caused by the change of processing stress and surface structure, and grinding caused by grain and other small defects);
4) The cutting edge is not processed (too sharp products will have zigzag shape under the microscopic condition, which will directly affect the use. After slight passivation treatment, the zigzag will be eliminated, and the service life will be doubled)
5) the use of equipment and processing conditions (good equipment and strict processing technology to promote our products in use can show the performance of the metal ceramic), in short, the service life of the tool and its details are closely related to the processing.
