what is tungsten carbide spray coating powder and how to spay

       

Spraying
coat is a kind of coating method, which is applied on the surface of the coated
object by spray gun or disc atomizer, dispersing into uniform and fine droplets
by means of pressure or centrifugal force. It can be divided into air spraying,
airless spraying, electrostatic spraying and various derivative ways of the
above basic spraying forms, such as large flow low pressure atomization
spraying, thermal spraying, automatic spraying, multi group spraying, etc.

Tungsten
carbide powder (WC) is the main raw material for producing cemented carbide. It
can be called wolfram carbide, or tungsten carbide. It is a black hexagonal
crystal with metallic luster and similar hardness to diamond. It is a good
conductor of electricity and heat. Tungsten carbide is insoluble in the mixed
acid of water and hydrofluoric acid. Pure tungsten carbide is fragile, if a
small amount of titanium, cobalt and other metals are added, the brittleness
can be reduced. Tungsten carbide, which is used as steel cutting tool, is often
added with titanium carbide, tantalum carbide or their mixture to improve the
antiknock ability.

Specifications

Tungsten
carbide powder formula: WC

Appearance:
dark gray powder

Application:
used for cemented carbide production materials; is widely used in high hardness
and strength of industrial tools, wear-resistant parts. Such as metal cutting
tools, drill bits, wear-resistant teeth, ceramic alloys, electronic contacts,
etc.

Impurity
content of WC powder: WC 10, WC 14, WC 18, WC 24, WC 30, WC40, WC 50, WC 70, WC
100, WC 140, WC 200

How
to spray?

Before
spraying, make preparations according to the chemical composition (coating
grade, etc.) of tungsten carbide powder.

In
engineering practice, tungsten carbide spraying is usually carried out in the
form of layered operation.

In
the process of operation, it is necessary to adjust or replace the mold in time
due to the mechanical reasons. In the spraying process, the air supply,
spraying speed, spraying quality and dosage should be judged or adjusted
according to the actual situation.
