Compound Particles and Product Manufactured Therefrom

Abstract

A compound particle and a product manufactured from the compound particles are provided to solve a problem of a rough surface of a product made by additive manufacturing technology. The compound particle has a metal core and a ceramic shell wrapping the metal core. A melting point of the ceramic shell is higher than a melting point of the metal core.

What is claimed is: 
     
         1 . A compound particle, comprising:
 a metal core; and   a ceramic shell wrapping the metal core, wherein a melting point of the ceramic shell is higher than a melting point of the metal core.   
     
     
         2 . The compound particle as claimed in  claim 1 , wherein the metal core comprises a material selected from titanium, stainless steel, aluminum alloy, titanium alloy, cobalt-chromium alloy, and nickel-based alloy. 
     
     
         3 . The compound particle as claimed in  claim 1 , wherein the metal core has a diameter between 30 and 120 μm. 
     
     
         4 . The compound particle as claimed in  claim 1 , wherein the ceramic shell comprises a material selected from tricalcium phosphate, hydroxyapatite, alumina, silicon carbide, silicon dioxide, titanium dioxide, and zirconia. 
     
     
         5 . The compound particle as claimed in  claim 1 , wherein the ceramic shell has a thickness between 50 and 100 nm. 
     
     
         6 . The compound particle as claimed in  claim 1 , wherein the melting point of the metal core is between 660 and 1700° C. 
     
     
         7 . The compound particle as claimed in  claim 6 , wherein the melting point of the ceramic shell is higher than 1700° C. but not higher than 2500° C. 
     
     
         8 . The compound particle as claimed in  claim 1 , wherein the melting point of the ceramic shell is between 1000 and 2500° C. 
     
     
         9 . The compound particle as claimed in  claim 8 , wherein the melting point of the metal core is not lower than 660° C. but lower than 1000° C. 
     
     
         10 . A product manufactured from compound particles, wherein the product is manufactured from the compound particles as claimed in claim
