Machining tungsten carbide coating.

We will get back to you withing 24 hours. Tungsten carbide hvof diamond grinding turnkey roll processing since every thermal cold spray coating project is unique asb industries develops specific combinations of surfacing technologies and machining procedures to ensure optimal component and equipment performance. Why is tungsten carbide an ideal tool material. Premium machining has state of art machines and technologies specifically adapted to machining of tungsten carbide.

This makes tialn a preferred choice when coating carbide. In its most basic form tungsten carbide is a fine gray powder but it can be pressed and formed into shapes through a process called sintering for use in industrial machinery cutting tools abrasives armor piercing shells and jewellery. Formerly seco carboloy told the story of how tungsten ore is processed into tungsten carbide which then becomes a state of the art cutting tool insert. This coating holds its hardness at higher temperatures due to a layer of aluminum oxide that forms between the tool and the cutting chip.

The tungsten carbide wc 12co coatings are resistant to sliding wear impact abrasion and fretting at temperatures up to 510 c 950 f preferably in non corrosive media. Carbide tooling is generally run at higher speeds compared to hss. This layer transfers heat away from the tool and into the part or chip. Tungsten carbide chemical formula.

Wc 12co thermal spray coatings are usually harder compared to coatings of wc 17co as a result of higher tungsten carbide levels in the coating. 2 issue 10 from ore to insert. Hvof applied coatings have a very strong bond and are hard and dense in nature. Today s machining world archive.

Tool choice is equally important. One alternative to sourcing and machining in tungsten would be to use tungsten carbide coating. If there is vibration your tools will chip similarly the machine tool used to cut tungsten must be rigid and resistant to vibration he notes. These coatings are produced by taking a powdered material in this case tungsten and heating them up and firing them out at extreme velocities where they liquify.

First class industrial coating services. With advanced equipment a skilled staff of thermal sprayers and machinists and extensive machining and grinding capabilities asb can provide unique thermal spray and cold spray solutions for extreme wear high temperature barriers and all encompassing part repair.
