The friction and wear properties of hot-pressed Al 2 O 3 -TiC-Co advanced ceramics (called ATC here), which have been made by use of Al 2 O 3 and TiC powders chemically coated with a cobalt film, have been studied in this paper with the help of a pin-on-disk apparatus in a scanning election microscope. The experiments show that the friction behavior of ATC varies with...
In a newly developed chemical deposition process, a layer of metal cobalt film is coated on the surface of ultrafine ceramic powders of Al 2 O 3 and TiC. The mixture of the two kinds of Co-coated powder (about 70 wt.%Al 2 O 3 -Co + 30 wt.%TiC-Co) is hot-pressed into advanced Al 2 O 3 -TiC-Co (ATC) ceramic. Scanning electron microscopy observation is...
