Quick Answer: How Strong Is Carbide? - Ceramics

What is the hardness of carbide? Hardness varies but all cemented carbides are harder than the hardest metals. Tungsten carbide with a Vickers number of 1700-2400 (85 HRC equivalent) is composed of 90% carbide particles by weight, 80% by volume. Most standard wear resistant alloys contain a maximum of 35% by volume of softer chromium carbide.

Features And Preparation Of Tungsten Carbide Mining Tool

In cemented carbide, WC particles form a strong skeleton, so WC cemented carbides exhibit very high hardness. In addition, WC belongs to the hexagonal crystal system and has anisotropy in hardness. The Vickers hardness of the bottom surface {0001} and the edge surface {1010} is 2 100 HV and 1 080 HV, respectively.

Carbonate Hardness - an overview | ScienceDirect Topics

The hardness compounds are taken into solution because the water becomes acidic as it acquires carbon dioxide from the soil formed by the oxidation of organic matter. A major source of non-carbonate hardness in surface waters is the calcium sulphate present in clays and other deposits.
