Carbide Thermal Spray Powder

1. What is carbide thermal spray powder?

Carbide thermal spray powder is a kind of hardfacing material which can make the surface of the

other metals, workpieces and large scale furnishments strength. It can be plated to the surface of

the workpieces which need to be harden by the way of Hvof or Plasma Spraying to make the

workpieces more wearable, heat-resistant erodent-resistant, concussion-resistant for a long life

using. It also can be used for making the coating with those special functions such as hermetical

function, heat insulation; insulation, superconduct etc. and it can be applied to many fields such

as metalworking, navigation, avigation and geological prospecting etc.

2. Product Peculiarity

Carbide Powders/ Tungsten Carbide/ Thermal Spray Powders

Air Plasma Spray/ HVOF/ Combustion Spray

Generally Tungsten carbide materials are recommended for wear applications wit service

temperatures of less than 500°C(930°C), as high temperatures will resulting the formation of

brittle phases that reduce wear resistance and coating integrity, manufacturing process,

individual carbide size and spray process are critical to overall performance, as is application

tribology. Typical wear applications include erosion (low angle), abrasion, fretting, sliding wear

and impact resistance. Matrixes of higher cobalt levels improve coating toughness. The addition

of chromium improves atmospheric corrosion. Powder selection and spray process is important

for applications with specific surface finish requirements.

Applications

Metal tungsten and tungsten carbide powders as raw materials are minxed,packed in

a graphite boat,melted in a melting furnace at about 2900℃,and held for a certain

time to obtain alloy casting block of cast tungsten carbide with main phases of W2C

and WC and grain particle size of 1-3um.particle is silver grey with metal luster.

Cast tungsten carbide is applied by oxygen-acetylene flame,arc,spray,braze and wet

welding on wear places.It is also adhered firmly to the surface of wear work pieces

with epoxy resin and inorganic additives at lower temperature and impact .The parts

of piled-up cast tungsten carbide coating can stand high temperature and impact .It

characterized by ling tool life,easy maintenance,low cost and improved productivity

In the production,equipment normally run is dependent on materials wear resistance

for wear parts in great degree .Selection of materisls with better wear resistance

provides longer equipment-life and stable running .Cast tungsten carbide as a wear

material is widely used in the mining, petroleum,construction and agricultural

machinery and steel industry etc.because of its high hardness(HRA93.0-93.7),good

wear resistance,easy piled-up welding and low cost.
