Abstract Porous carbide-derived carbons (CDCs) are synthesized by chlorination of carbides with different carbon volume fractions in the temperature range from 400 to 1000 °C. It is found that the volume fraction of carbon atoms in carbide precursor has much influence on pore structure of the produced CDC. It is prone to form well ordered graphite to

Effect of carbide volume fraction on erosive wear behaviour of hardfacing cast irons
Wear, 2004Abstract The present work reports the effect of carbide volume fraction on erosive wear behaviour of hardfacing cast irons. Five different grades of weld hardfacing cast irons were selected for the present investigation. The solid particle erosion experiments were carried out with blast furnace sinter, silica sand and alumina particles under mild (53–

Wear, 2022
The addition of NbC to high chromium white cast irons (WCIs) has potential to improve component wear lives in mining and ore beneficiation environments, due to the combined presence of Cr-rich and niobium carbides. While the effect of chromium carbide volume fraction (Cr-CVF) on abrasion performance of plain-Cr WCIs is well understood, its effect on ...

A new analytical procedure was developed for estimating volume fractions of primary carbides in tool steels. The method utilizes electrolytic extraction of carbides, EDX analysis, and X-ray powder diffraction. Chemical compositions of individual carbide species are compared with the bulk carbide composition to find weight fractions of each species, and

Abstract High chromium white cast irons display a number of advantages in abrasive wear applications. Their composition may be adjusted so that they contain moderate amounts of chromium yet solidify to produce massive chromium-rich carbides in an austenitic matrix of sufficient hardenability to be transformed to martensite with relatively simple heat

Composites Part B: Engineering, 1999
Abstract An understanding of the work hardening behaviour of particulate reinforced metal–matrix composites is crucial in optimizing the parameters for deformation processing of these materials. In the case of particulate-reinforced aluminium composites, the microstructure and mechanical properties can be altered by thermomechanical treatments as ...

The fabrication of high volume fraction (HVF) M7C3 (M=Cr, Fe) reinforced Fe-based composite coating on ASTM A36 steel plate using plasma transferred arc (PTA) welding was studied. The results showed that the volume fraction of carbide M7C3 was more than sixty percent, and the relative wear resistance of the coating tested on a block-on-ring dry sliding
