Abstract:
1. A method for manufacturing a coating material for parts of an engine exhaust system, comprising: changing an inside of a chamber from a vacuum state to a plasma state; optionally depositing a first junction layer of Ti or Cr on a surface of a substrate disposed in the chamber; depositing a second junction layer of CrN or Ti(C)N on a surface of the first junction layer or on a surface of the substrate; depositing a support layer of TiAlN/CrN on a surface of the second junction layer; and depositing a functional layer of TiAlN/CrSiN or TiAlN/CrSiCN on a surface of the support layer, wherein the depositing of the functional layer made of TiAlN/CrSiN is performed by depositing the functional layer so that Ti, Al, Cr and Si are provided in the functional layer at a ratio of 1:1:0.9:0.1, wherein the depositing of the functional layer made of TiAlN/CrSiCN is performed by depositing the functional layer so that Ti, Al, Cr, Si and C are provided in the functional layer at a ratio of 1:1:0.8:0.1:0.1.
