Abrasion of ultrafine WC-Co by fine abrasive particles
Transactions of Nonferrous Metals Society of China, 2007 Abstract Abrasive wear of a series of WC-(5%-14%, mass fraction) Co hardmetals was investigated employing coarse and fine SiC abrasive under two-body dry abrasion conditions with pin-on-disc and edge-on-disc test arrangements. Unexpectedly, it is found that submicron grades demonstrate substantially higher wear rates comparing with the coarse grades ...

Acceleration of Abrasive Particles in Premixed Abrasive Water Jet Nozzle.
JSME International Journal Series B, 1996 It has been shown that the premixed abrasive water jet system has a greater capacity for drilling and cutting than the conventional abrasive water jet system. In the present investigation, the motion of spherical particles in a premixed abrasive water jet nozzle is investigated theoretically.

Abrasive Disc Performance in Dry-Cutting of Medium-Carbon Steel
Metals, 2020 Abrasive-cutting processes are widely used to obtain semi-finished products from metal bars, slabs, or tubes. Thus, the abrasive cutting-off process is applied when requiring precision cutting and productivity at a moderate price. Cut-off tools are discs
