Abstract:
A metallic porous product for producing a composite product, said metallic porous product being produced as a metallic skeleton structure by applying a slurry of a skeleton constituent material to an inflammable foam having open pores, burning away said inflammable foam so as to form a metallic skeleton structure, and sintering said metallic skeleton structure, said skeleton constituent material comprising:powder of a metal selected from a group of nickel (Ni) and nickel alloys; andabrasion resistance modifying particles comprising chromium (Cr) particles that are alloyed with said metal and ceramic particles, both said chromium (Cr) particles and said ceramic particles being dispersed in said powder of said metal;wherein said metallic skeleton structure has a Vickers hardness greater than 190, a porous volume of approximately 5 to 20% and a ceramic content of approximately 5 to 30 weight % of said metallic skeleton structure.
