Boron carbide (B4C)based ceramics were pressureless sintered to a relative density of % at 2150 °C, with the coincorporation of tungsten carbide and pyrolytic carbon.
A compound as hard as tungsten carbide is also less forgiving of the rapid loads from torque introduced by an injection molding machine. "The brittleness is, of course, a consideration," says Colby. "But we don't know where we stand with that." Colby says Spirex has spent several weeks testing the screw on a 120ton Toshiba, molding ABS parts. He says he has not encountered problems with ...
Hardmetals are tungsten carbide (WC)based composites, which are made of WC as a hard phase and transition metals such as Co, Fe, or/and Ni as ductile binder matrices. Their properties can be ...
· When tungsten is forged with carbon and becomes tungsten carbide, it forms covalent bonds and becomes very hard but also brittle. Tungsten carbide rings can't be resized for two reasons: they are too brittle, and their atomic bonding, which forms .

Tungsten carbide powder market will reach an estimated valuation of USD million by 2027, while registering this growth at a rate of % for the forecast period of 2020 to 2027. Tungsten carbide powder can be define as chemical compound containing atoms of tungsten and carbide which can be moulded into various shapes for usage in ...
· The performance of tungsten carbide even surpassed that of Pt, and a substantial increase (∼25%) in energy conversion efficiency was achieved when Pt was substituted by tungsten carbide film as the counter electrode. In addition, tungsten carbide displayed decent activity as a alyst for the hydrogen evolution reaction, suggesting the high feasibility for its utilization as a .
Tungsten carbide cutters, or rather, rotary instruments in general are part of the dental technicians daily routine. "We need high quality products that support us during our work and reliably deliver good results", says dental technical Christian Schuchmann (Manager .

Again, he says he won't know until he gets volunteers willing to help test the screw. If you're a molder willing to try the tungsten carbide screw, Spirex will offer it for a reduced price if you're also willing to cooperate on testing and share performance data. Call Paul Colby at .
· In this study, ductile mode chip formation in conventional cutting and ultrasonic vibration assisted cutting of tungsten carbide workpiece material has been investigated through experimental grooving tests using CBN tools on a CNC lathe. The experimental results show that as the depth of cut was increased there was a transition from ductile mode to brittle mode chip formation in grooving both ...
· Cemented tungsten carbide has been analyzed using laserpulsed atom probe tomography (APT). The influence of experimental parameters, including laser pulse energy, pulse repetition rate, and specimen base temperature, on the acquired data were evaluated from different aspects, such as mass spectrum, chemical composition, noisetosignal ratio, and multiple events.
