Aqueous Processing of WC-Co Powders

Sintering and Characterizations of WC-20wt.% (Fe,Co) Nano-Structured Powders Developed by Ball-Milling

The aim of the present work is to study the effects of the nanostructured WC-20 wt. % (Fe,Co) with different ratios of iron to cobalt on the microstructure and hardness of sintered samples. Furthermore, a sample with a cobalt binder under the same condition was produced for the comparison purposes. The nanocomposite development, after different milling times, has been monitored by means of X-ra...

Magnetic and Structural Characterisation of PbFe12-xCrxO19 (1.0 x 6.0) Hexaferrites Powders Obtained by Coprecipitation Method

The present work describes the preparation of chromium substituted magnetoplumbite ferrites from nitrate salts, and the effect of Cr on its structural and magnetic properties. Powders with nominal composition PbFeiz,Cr,O,, (1.0 < x S 6.0) were obtained by thermal decomposition at 920 "C of coprecipitated hydroxide-carbonate mixed salts. A complete substitution of Fe3* by cr3' was found and the ...

Preparation of Property-Controlled Bi-Based Solder Powders by a Ball-Milling Process

Three kinds of Bi-based solder powders with different chemical compositions of binary Bi–Sn, ternary Bi–Sn–In, and quaternary Bi–Sn–In–Ga were prepared using a gas atomization process and subsequently ball-milled for smaller-size fabrication. In particular, only the quaternary Bi–Sn–In–Ga solder powders were severely broken to the size of less than 10 μm in a polyhedral shape due to the presenc...

Effect of Grinding Parameters on the Fracture Toughness of WC–10Co–4Cr Coating Deposited by HVOF

Nowadays, application of cermet coatings deposited by High-Velocity Oxygen-Fuel (HVOF) has received considerable attention in a variety of industries. Carbide coatings have high surface roughness, so it is essential to grind the coated surface. The present investigation studied the effect of simultaneous changes in the grinding parameters including the depth of cut, feed rate and cutting sp...
