Machining tungsten carbide coating.

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. This coating holds its hardness at higher temperatures due to a layer of aluminum oxide that forms between the tool and the cutting chip. Premium machining has state of art machines and technologies specifically adapted to machining of tungsten carbide. Why is tungsten carbide an ideal tool material.

Tool choice is equally important. Don graham turning products manager at seco tools inc. 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. 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.

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. We will get back to you withing 24 hours. 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. First class industrial coating services.

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. This layer transfers heat away from the tool and into the part or chip. 2 issue 10 from ore to insert. One alternative to sourcing and machining in tungsten would be to use tungsten carbide coating.

Wc is a chemical compound specifically a carbide containing equal parts of tungsten and carbon atoms. Hvof applied coatings have a very strong bond and are hard and dense in nature. I find you need a high positive cutting edge and the right carbide grade and coating mr. This makes tialn a preferred choice when coating carbide.

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. Tungsten carbide chemical formula.
