Abstract

A method for prolonging service life of a machine for bending tubes comprises flame spraying a coating of less than 0.1 mm of molybdenum or molybdenum alloy to at least one surface of a fold smoothing tool.

Claims

exact text as granted — not AI-modified
1 - 2 . (canceled) 
   
   
       3 . A method for prolonging service life of a machine for bending tubes, the method comprising flame spraying a coating of less than 0.1 mm of molybdenum or molybdenum alloy to at least one surface of a fold smoothing tool. 
   
   
       4 . The method of  claim 3 , further comprising flame spraying a coating of less than 0.1 mm of molybdenum or molybdenum alloy to at least one surface of a mandrel. 
   
   
       5 . The method of  claim 3 , further comprising flame spraying a coating of less than 0.1 mm of molybdenum or molybdenum alloy to at least one surface of one or more rollers. 
   
   
       6 . The method of  claim 3 , further comprising flame spraying a coating of less than 0.1 mm of molybdenum or molybdenum alloy to at least one surface of one or more guide aids. 
   
   
       7 . The method of  claim 3 , further comprising flame spraying a coating of less than 0.1 mm of molybdenum or molybdenum alloy to at least one surface of one or more dies. 
   
   
       8 . The method of  claim 3 , further comprising flame spraying a coating of less than 0.1 mm of molybdenum or molybdenum alloy to at least one surface of one or more guide rails. 
   
   
       9 . A method for prolonging service life of a machine for bending tubes, the method consisting of flame spraying a coating of less than 0.1 mm of molybdenum or molybdenum alloy to at least one surface of a fold smoothing tool. 
   
   
       10 . The method of  claim 9 , further consisting of flame spraying a coating of less than 0.1 mm of molybdenum or molybdenum alloy to at least one surface of a mandrel. 
   
   
       11 . The method of  claim 9 , further consisting of flame spraying a coating of less than 0.1 mm of molybdenum or molybdenum alloy to at least one surface of one or more rollers. 
   
   
       12 . The method of  claim 9 , further consisting of flame spraying a coating of less than 0.1 mm of molybdenum or molybdenum alloy to at least one surface of one or more guide aids. 
   
   
       13 . The method of  claim 9 , further consisting of flame spraying a coating of less than 0.1 mm of molybdenum or molybdenum alloy to at least one surface of one or more dies. 
   
   
       14 . The method of  claim 9 , further consisting of flame spraying a coating of less than 0.1 mm of molybdenum or molybdenum alloy to at least one surface of one or more guide rails. 
   
   
       15 . A method for prolonging service life of a machine for bending tubes, the method comprising electroplating or vapor depositing a coating of less than 0.1 mm of molybdenum or molybdenum alloy to at least one surface of a fold smoothing tool. 
   
   
       16 . The method of  claim 15 , further comprising electroplating or vapor depositing a coating of less than 0.1 mm of molybdenum or molybdenum alloy to at least one surface of a mandrel. 
   
   
       17 . The method of  claim 15 , further comprising electroplating or vapor depositing a coating of less than 0.1 mm of molybdenum or molybdenum alloy to at least one surface of one or more rollers. 
   
   
       18 . The method of  claim 15 , further comprising electroplating or vapor depositing a coating of less than 0.1 mm of molybdenum or molybdenum alloy to at least one surface of one or more guide aids. 
   
   
       19 . The method of  claim 15 , further comprising electroplating or vapor depositing a coating of less than 0.1 mm of molybdenum or molybdenum alloy to at least one surface of one or more dies. 
   
   
       20 . The method of  claim 15 , further comprising electroplating or vapor depositing a coating of less than 0.1 mm of molybdenum or molybdenum alloy to at least one surface of one or more guide rails.
