Method for Coating Components

Abstract

A method for coating components, particularly engine components, includes the steps of: producing a coating material by or when melting, fusing and/or incipient melting a material, for a first coating method; and using this coating material at least partly in a second coating method.

What is claimed is: 
     
         1 . A method for coating components, comprising the steps of:
 producing a coating material by or during melting or incipient melting of a feedstock for a first coating process; and   at least partially using the coating material for a second coating process.   
     
     
         2 . The method according to  claim 1 , further comprising the step of:
 melting or incipiently melting a wire feedstock.   
     
     
         3 . The method according to  claim 2 , wherein
 the second coating process is cold gas spraying.   
     
     
         4 . The method according to  claim 1 , wherein
 the second coating process is cold gas spraying.   
     
     
         5 . The method according  claim 1 , wherein
 the first coating process is a thermal spraying process.   
     
     
         6 . The method according  claim 5 , wherein
 the thermal spraying process is wire arc spraying.   
     
     
         7 . The method according to  claim 1 , further comprising the steps of:
 producing the coating material during performance of the first coating process; and   collecting the coating material during or after performance of the first coating process.   
     
     
         8 . The method according  claim 1 , further comprising the step of:
 performing the first coating process in an oxygen-free environment or in an at least oxygen-poor environment.   
     
     
         9 . The method according to  claim 1 , further comprising the steps of:
 performing the first coating process in an extracted enclosure; and   extracting and storing the excess coating material.   
     
     
         10 . The method according to  claim 1 , further comprising the steps of:
 providing a cylinder head and a crankcase;   coating the crankcase in the first coating process; and   coating the cylinder head in the second coating process.   
     
     
         11 . The method according to  claim 1 , further comprising the step of:
 separating the first and second coating processes spatially and/or temporally.   
     
     
         12 . The method according to  claim 1 , wherein
 the coating components are engine components.   
     
     
         13 . A method of use, comprising:
 use of a first coating process for producing a coating material;   using the coating material for a second coating process.   
     
     
         14 . A coating material produced by a process according to  claim 1 , wherein the coating material is pulverulent. 
     
     
         15 . The coating material according to  claim 14 , wherein a majority of the particles have a diameter of 5 to 150 μm. 
     
     
         16 . The coating material according to  claim 14 , wherein a majority of the particles have a diameter of 15-80 μm. 
     
     
         17 . The coating material according to  claim 14 , wherein the coating material has an Fe proportion of at least 94%. 
     
     
         18 . The coating material according to  claim 14 , wherein the coating material has an Fe proportion of at least 68% and a Cu proportion of up to 14%.
