Coated silicon nitride based cutting tools |
摘要 |
The present invention relates to coated silicon nitride based cutting tools and a method of making the same. By a carburizing heat treatment prior to the deposition of the coating an improved bonding strength of the coating is obtained. A continuous or semicontinuous transition zone of 2-10 mu m thickness is formed between the substrate and the inner layer of the coating in which transition zone the glass phase is replaced by the material of the inner layer. <IMAGE> |
