Jun 24, 2017· I realize that there are different techniques for binding carbide into a final tool shape, however by question is on a lower chemistry level. Carbide by it's strict definition is a binary compound of carbon with a lower electro-negativity element. So in theory there are many types of carbide: boron carbide, calcium carbide, tungsten carbide etc.
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 .

Silicon carbide (SiC), also known as carborundum / k ɑːr b ə ˈ r ʌ n d əm /, is a semiconductor containing silicon and carbon.It occurs in nature as the extremely rare mineral moissanite.Synthetic SiC powder has been mass-produced since 1893 for use as an abrasive.Grains of silicon carbide can be bonded together by sintering to form very hard ceramics that are widely used in applications ...
Boron carbide (B 4 C) has higher hardness than alumina or silicon carbide. Its oxidation product (B 2 O 3 ) provides a protective skin at high temperatures (> 800 o C). Because of its high hardness and wear resistance, boron carbide is applied in low-temperature applications such as grinding wheel dressers, and abrasive blast or water jet nozzles.

Mohs' Hardness (Typical) of Abrasives table from READE. Abrasive blasting for surface preparation is an important step in providing a foundation for protective coatings. For years, tests have concluded that high-performance coatings provide excellent corrosion protection and durability when applied over a blast-cleaned surface with a consistent anchor profile.
Sep 29, 2017· Calcium carbide is a chemical compound with numerous industrial applications. When combined with water, it produces acetylene gas, which is used in welding and cutting torches. According to the Hong Kong Trade Development Council, calcium carbide also constitutes a key component of most polyvinyl chloride (PVC) produced in China.
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.
CALCIUM CARBIDE Hardness The hardness curve for the CaC2-CaCo system was determined by the monotron method, in which the load required to press a diamond indenter a standard depth into the specimen in a measure a generally rising hardness from that of calcium carbide .
Nov 01, 2017· Measure out enough calcium chloride to raise the hardness level. Use 1 1/4 pounds of product per every 10,000 gallons of water if you need to raise the level by 10 ppm. Use 2 1/2 pounds (per 10,000 gallons) to raise the level by 20 ppm, or use 6 1/4 pounds of product (per 10,000 gallons) to raise the hardness level by 50 ppm.
