Abstract

A coating for turbomachinery comprises graphite-based sold film lubricant material.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A coating for turbomachinery, the coating comprising: graphite-based sold film lubricant material. 
     
     
         2 . A coating for turbomachinery according to  claim 1 , wherein the coating provides at least one of crevice corrosion resistance and fretting resistance. 
     
     
         3 . A coating for turbomachinery according to  claim 1 , wherein turbomachinery comprises at least a wheel comprising a slot and a bucket comprising a dovetail, the coating is applied to at least one of the slot and the dovetail. 
     
     
         4 . A coating for turbomachinery according to  claim 3 , wherein the coating is applied to the dovetail. 
     
     
         5 . A coating for turbomachinery according to  claim 3 , wherein the turbomachinery comprises a superalloy material. 
     
     
         6 . A coating for turbomachinery according to  claim 1 , the coating comprises graphite-based dry film lubricants. 
     
     
         7 . A coating for turbomachinery according to  claim 1 , the coating comprises metal filled resin based systems. 
     
     
         8 . A coating for turbomachinery according to  claim 1 , the coating further comprises at least one of silicate binder with graphite and high temperature lubricating additives. 
     
     
         9 . A coating for turbomachinery, the coating comprising:
 graphite-based sold film lubricant material;   the turbomachinery comprises at least a wheel comprising a slot and a bucket comprising a dovetail, the coating is applied to at least one of the slot and the dovetail;   and coating comprises at least one of:
 graphite-based dry film lubricants, metal filled resin based systems, silicate binder with graphite; and high temperature lubricating additives. 
   
     
     
         10 . A coating for turbomachinery according to  claim 9 , wherein the coating is applied to the dovetail. 
     
     
         11 . A coating for turbomachinery according to  claim 9 , wherein the turbomachinery comprises a superalloy material. 
     
     
         12 . A coating for turbomachinery according to  claim 9 , wherein the coating provides at least one of crevice corrosion resistance and fretting resistance. 
     
     
         13 . A method for coating for turbomachinery to provide at least one of crevice corrosion resistance and fretting resistance, the method comprising:
 providing a coating; and   applying the coating to at least one of the slot and the dovetail;
 wherein the coating comprises: 
 graphite-based sold film lubricant material;
 the turbomachinery comprises at least a wheel comprising a slot and a bucket comprising a dovetail, the coating is applied to; and 
 the coating comprises at least one of graphite-based dry film lubricants, metal filled resin based systems, silicate binder with graphite; and high temperature lubricating additives.
