Thermal Spray molybdenum wire is a refractory metal with melting point up to 2630 ° C. Because molybdenum and hydrogen does not react, it’s used as a high temperature coating under hydrogen protection or vacuum conditions. And due to the low friction coefficient of molybdenum, it’s suitable for spray the piston rings and the friction plate wear-resistant coating.
Tungsten is a metallic chemical element classified among the transition metals of the periodic table of elements. It is well known for its strength and durability, which make it extremely useful in a wide range of industrial applications.
The term “tungsten carbide” describes a comprehensive family of hard carbide compositions used for metal cutting tools, dies of various types, and wear parts. In general, these materials are composed of the carbides of tungsten, titanium, tantalum, or some combination of these, sintered or cemented in a matrix binder, usually cobalt.
Tungsten carbide, WC, or tungsten semi-carbide, W2C, is a chemical compound containing tungsten and carbon, similar to titanium carbide. Colloquially, tungsten carbide is often simply called carbide.
Most tungsten concentrates are processed chemically to ammonium paratungstate (APT). Secondary raw materials like (oxidized) scrap and residues are another important feed for chemical tungsten process
Since the introduction of titanium and titanium alloys in the early 1950s, these materials have in a relatively short time become backbone materials for the aerospace, energy, and chemical industries.
According to the China Defense Science and Technology Information Network reported that the US is expected to develop a new tungsten-chrome-ferro(WcrFe) alloy for armor-piercing to replace the deplete
