Diffusion bonding of hardmetals (WC-Co) to themselves or with other metallic material (mildsteel) has been evaluated in the present paper. Metallographic studies and mechanical tests have been used to determinate the influence of the bonding parameters (temperature, pressure and time) on the bond microstructure and strength. Different metallic interlayers applied in form of thick foils were use...

The exploration of coarse-grained WC cemented carbide has become a research hotspot for its application in the fields rock cutting and mining; key issue is how to achieve uniform dispersion densification sintered phase, as well obtain better mechanical properties. In this paper, chemical co-precipitation, combined with hydrogen reduction, was adopted. CoCl2·6H2O CeCl3 were used precursors coat ...

BACKGROUND WHITE COLLAR-1 (WC-1) mediates interactions between the circadian clock and the environment by acting as both a core clock component and as a blue light photoreceptor in Neurospora crassa. Loss of the amino-terminal polyglutamine (NpolyQ) domain in WC-1 results in an arrhythmic circadian clock; this data is consistent with this simple sequence repeat (SSR) being essential for clock f...

The co-hydrothermal carbonization (Co-HTC) of polyvinyl chloride (PVC) film and wood chip (WC) was conducted at 200-260oC in an autoclave filled air or nitrogen for the chemical recycling wastes with dechlorination PVC. Effects Co-HTC temperature oxidation reaction during on decomposition behaviors were investigated. percentage atmosphere increased increasing reached 76.1% 260oC. decompositions...

Bu çalışmada tungsten karbür - kobalt (WC-Co) besleme stoğundan Toz Enjeksiyon Kalıplama (TEK) yöntemi ile elde edilmiş numunelerin kimyasal bağlayıcı aşamasında kullanılacak çözücü türü araştırılmıştır. TEK WC-Co hazırlanan deney numunelerinin giderme deneyleri onüç farklı (Toluen, Benzen, Heptan, Aseton, Etanol, Karbon tetraklorür (CCl4), Etanol+ Metanol, Nitrik asit, Hidroklorik Sülfürik Klo...
