Abstract

Disclosed is a coating material for parts of an engine exhaust system and a method for manufacturing the same. The coating material includes a second junction layer made of CrN or Ti(C)N, a support layer made of TiAlN/CrN disposed on a surface of the second junction layer, and a functional layer made of TiAlN/CrSiN or TiAlN/CrSiCN disposed on a surface of the support layer. The coating material improves abrasion resistance and seizure resistance of the parts of the engine exhaust system.

Claims

exact text as granted — not AI-modified
1 . A coating material for parts of an engine exhaust system, comprising:
 a second junction layer made of CrN or Ti(C)N;   a support layer made of TiAlN/CrN disposed on a surface of the second junction layer; and   a functional layer made of TiAlN/CrSiN or TiAlN/CrSiCN disposed on a surface of the support layer.   
     
     
         2 . The coating material for parts of an engine exhaust system of  claim 1 , wherein the second junction layer has a thickness of about 0.1 to about 10 μm, the support layer has a thickness of about 0.5 to about 10 μm, and the functional layer has a thickness of about 0.5 to about 10 μm. 
     
     
         3 . The coating material for parts of an engine exhaust system of  claim 1 , further comprising a first junction layer made of Ti or Cr on a surface of which the second junction layer is disposed. 
     
     
         4 - 9 . (canceled)
