          Application 08/826,209                                                      


          having a {100} crystallographic faceting layer and a non-{100}              
          crystallographic faceting layer.  Claims 1 and 7 are                        
          illustrative:                                                               


               1.  A method for making a diamond film coated wear part,               
          comprising the steps of:                                                    
               providing a wear part;                                                 
               depositing a first layer of polycrystalline diamond film               
          on said part with non-{100} crystallographic faceting;                      
               depositing on the surface of said first layer a second                 
          layer of polycrystalline diamond film having {100}                          
          crystallographic faceting, said second layer having a                       
          thickness sufficient to overgrow the roughness of said surface              
          of said first layer with a continuous film.                                 
               7.  A method of making a wear component, comprising the                
          steps of:                                                                   
               providing a base surface;                                              
               producing a polycrystalline diamond film structure having              
          a first layer and a second layer on said first layer, said                  
          first layer having non-{100} crystallographic faceting, and                 
          said second                                                                 
          layer having {100} crystallographic faceting, said second                   
          layer having a thickness sufficient to overgrow the roughness               
          of said surface of said first layer with a continuous film;                 
          and                                                                         
               applying said diamond film to said base surface.
