Tungsten and tungsten carbide are materials proposed for extreme environment applications such as first plasma face or cutting tools The high melting temperature and strong bonding energy of both materials force the use of powder metallurgical processes and non-conventional sintering routes to achieve dense parts In the wet milling process the boron powder and tungsten carbide ball were put into the milling jar as in the dry milling process Also 15 ml of anhydrous hexane (Sigma-Aldrich purity of 95%) as a solvent and 1 ml of oleic acid (Sigma-Aldrich USA) as a coating material were added to the milling jar Get Price Online Chat


Titanium Forceps are light weight In fact they are 45% lighter than the Stainless Steel Forceps They are anti-magnetic and much harder than stainless steel forceps Titanium is non-corrosive therefore immune from the rust Titanium Forceps have longer utility life than any steel material

TUNGSTEN CARBIDE/TUNGSTEN ALLOYS Tungsten carbide formerly also referred to colloquially as Widia (as hard as diamond) is a material that is produced via a sintering process and that consists of very hard tungsten carbide (often tungsten carbide + cobalt which are bonded together in a metallic matrix)

The potential of copper oxide (CuO) and tungsten carbide (WC) nanofluids in enhancing micropitting and wear behavior of AISI 8620 steel under boundary lubrication conditions was investigated The nanofluids consisted of 1% nanoparticles by weight and 1% by weight of oleic acid surfactant in Polyalphaolefin (PAO)

Tungsten is commonly alloyed with carbon forming tungsten carbide which has a very high melting point and increased hardness It is used in high-strength applications such as furnaces missiles dental drills and other cutting tools The symbol for tungsten W comes from tungsten's Latin name Wolfram

1 Introduction When metals such as titanium or tungsten are incorporated into diamond-like carbon coatings nanocomposite materials consisting of nanocrystalline metal carbide precipitates in amorphous carbon or hydrocarbon matrices are formed The enhanced durability and mechanical strength of MC/a-C or MC/a-C:H thin film coatings renders them very effective

Strontium is the chemical element with the symbol Sr and atomic number 38 An alkaline earth metal strontium is a soft silver-white yellowish metallic element that is highly chemically reactive The metal forms a dark oxide layer when it is exposed to air Strontium has physical and chemical properties similar to those of its two vertical neighbors in the periodic table calcium
