Machining Tungsten Carbide Coating

Hvof applied coatings have a very strong bond and are hard and dense in nature.

Machining tungsten carbide coating.

One alternative to sourcing and machining in tungsten would be to use tungsten carbide coating. 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. First class industrial coating services. 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.

Today s machining world archive. Tool choice is equally important. 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. I find you need a high positive cutting edge and the right carbide grade and coating mr.

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. This makes tialn a preferred choice when coating carbide. We will get back to you withing 24 hours. Why is tungsten carbide an ideal tool material.

Don graham turning products manager at seco tools inc. Tungsten carbide chemical formula. This coating holds its hardness at higher temperatures due to a layer of aluminum oxide that forms between the tool and the cutting chip. 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.

Wc is a chemical compound specifically a carbide containing equal parts of tungsten and carbon atoms. 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. 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 layer transfers heat away from the tool and into the part or chip.

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 is the most widely used type of high speed machining hsm tool material produced by powder metallurgy consisting of hard carbide usually tungsten carbide wc particles and a softer metal bond.
