Abstract

A coating layer with well protection and thermal conductivity has a workpiece; and a coating layer with a thickness ranged between 160˜500 micrometer deposited on the workpiece; wherein, the coating layer is formed by the feedstock material, the feedstock material is Al—Cu—Mo—W, Al/B 4 C, CoCrAlY/Al 2 O 3 , Cr 3 C 2 —NiCr/SiC—Ni, Cr 3 C 2 —NiCr/SiC—Ni treated with Ball mill or Ni—Al—Mo—W. The coating layer is able to avoid wear of the surface of the workpiece, and has well protection and thermal conductivity, to avoid the situation of damage or mechanical property changing occurred due to the temperature of the surface rising caused by the friction.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A coating layer with well protection and thermal conductivity comprising:
 a workpiece; and   a coating layer with a thickness ranged between 160˜500 micrometer deposited on the workpiece;   wherein, the coating layer is formed by the feedstock material, the feedstock material is Al—Cu—Mo—W, Al/B 4 C, CoCrAlY/Al 2 O 3 , Cr 3 C 2 —NiCr/SiC—Ni, Cr 3 C 2 —NiCr/SiC—Ni treated with Ball mill or Ni—Al—Mo—W.   
     
     
         2 . The coating layer of  claim 1 , wherein a composition of Al—Cu—Mo—W is 30˜35 wt % Al—Cu, 30˜35 wt % Mo and 30˜35 wt % W. The best composition of Al—Cu—Mo—W is 33.3 wt % Al—Cu, 33.3 wt % Mo and 33.3 wt % W. 
     
     
         3 . The coating layer of  claim 1 , wherein a composition of Al/B 4 C is 20˜40 wt % B4C. 
     
     
         4 . The coating layer of  claim 1 , wherein a composition of CoCrAlY/Al2O3 is 10˜20 wt % Al 2 O 3 . 
     
     
         5 . The coating layer of  claim 1 , wherein a composition of Cr3C2-NiCr/SiC—Ni is 20˜40 wt % SiC—Ni. 
     
     
         6 . The coating layer of  claim 1 , wherein a composition of Cr3C2-NiCr/SiC—Ni treated with Ball mill is 20˜40 wt % SiC—Ni. 
     
     
         7 . The coating layer of  claim 1 , wherein a composition of Ni—Al—Mo—W is is 30—35 wt % Ni-5Al, 30˜35 wt % Mo and 30˜35 wt % W.
