Cutting tool materials must be harder than the material of the workpiece, even at high temperatures during the process. The following properties are required for cutting tool materials: [1] hardness, hot hardness and pressure resistance; bending strength and toughness; inner bonding strength; wear resistance. oxidation resistance
As a result of their unique properties, these materials are of great interest in many industrial areas including, but not limited to, abrasives, polishing and cutting tools, disc brakes, and wear-resistant and protective coatings. Diamond is the hardest known
Tool steel is any of various carbon steels and alloy steels that are particularly well-suited to be made into tools and tooling, including cutting tools, dies, hand tools, knives, and others. Their suitability comes from their distinctive hardness , resistance to abrasion and deformation, and their ability to hold a cutting edge at elevated ...
High-speed steel (HSS or HS) is a subset of tool steels, commonly used as cutting tool material. It is superior to high-carbon steel tools in that it can withstand higher temperatures without losing its temper (hardness). This property allows HSS to cut faster than high carbon steel, hence the name high-speed steel.
Tungsten carbide (chemical formula: WC) is a chemical compound (specifically, a carbide) containing equal parts of tungsten and carbon atoms. In its most basic form, tungsten carbide is a fine gray powder, but it can be pressed and formed into shapes through sintering [7] for use in industrial machinery, engineering facilities, [8] molding blocks, [9] cutting tools, chisels, abrasives, armor ...
A variety of blade materials can be used to make the blade of a knife or other simple edged hand tool or weapon, such as a sickle, hatchet, or sword. The most common blade materials are carbon steel, stainless steel, tool steel, and alloy steel. Less common materials in blades include cobalt and titanium alloys, ceramic, obsidian, and plastic.
Molybdenum carbide is an extremely hard, refractory, ceramic material, commercially used in tool bits for cutting tools. There are at least three reported phases of molybdenum carbide: γ-Mo C, β-Mo 2 C, and γ'. The γ phase is structurally identical to tungsten carbide. [1] β-Mo 2 C has been suggested as a catalyst for carbon dioxide ...
At carbon contents higher than approximately ZrC 0.98 the material contains free carbon. [5] ZrC is stable for a carbon-to-metal ratio ranging from 0.65 to 0.98. The group IVA metal carbides, TiC , ZrC, and SiC are practically inert toward attack by strong aqueous acids (HCl) and strong aqueous bases (NaOH) even at 100' C, however, ZrC does ...
