Formed by a special sintering process.
Sintering process affects the property of tungsten alloy shield.
They are manufactured through either a casting or sintering process.
During the sintering process. Densities achieved by this method are typically in the range of.
One trick for producing WCu in higher densities is to add nickel during the sintering process.
In order to control the shrinkage difference between matrix and coating during sintering process, it is necessary to add a trace element in the preparation process to control the contraction of the two to reach the same.
Our Pusher furnaces provide the high temperature capability required, along with hydrogen atmosphere and dewpoint control for nuclear fuel sintering processes.
Tungsten copper activated liquid phase sintering canimprove the miscibility between tungsten and copper and promote the sintering process by means of adding a small amount of Co, Ni, Fe, Pd and other activated elements.
The high temperature liquid phase sintering process of discovery, tungsten, copper powder particle size also affects the sintered tungsten-copper composite material density, the finer the powder, the higher the density obtained by sintering. .
And then the resultant coating is put together with the matrix into a self-made special sintering furnace, and the sintering process is carried out using the temperature gradient.
During sintering process should wrap the molybdenum disilicide powder, cut off the air, which can prevent MoSi2 oxidative decomposition at about 500 ℃, so using the secondary sintering method can improve the sensitivity and resistance of the slurry sintering resistance dispersion.
At the beginning of 1990s, FGM(functionally graded material) has developed rapidly and additional temperature laser scanning sintering process has been introduced in FGM process. .
PM(Powder Metallurgy): It uses fine tungsten and copper powder, through impregnation sintering process, can withstand nearly 2000 ℃ and high stress, with high melting point, high hardness, anti-burning and good anti-adhesion, high surface finish of corrosion products, high accuracy, low consumption; 2.
Tungsten copper high temperature liquid phase sintering is use the tungsten powder andcopper powder by mixing, pressing, liquid phase sintering process for the system tungsten copper alloy.
The following describes two typical tungsten-copper-activated liquid phase sintering process: 1, W powder, Cu powder and a small amount of Ni, Co or Fe powder additive heptane after drying 24h in a ball mill and sieved, and then by press-forming, and finally the protection of the H2, sintered at 1250~ 1400 ℃ 1h conditions.
Tungsten carbide ball for pens is shaped by hard refractory metal compounds tungsten carbide and cobalt, and with sintering process to get the formation of a tungsten carbide substrate fake alloys.
Compared with the XRD spectrum of W-Cu and W-Cu/AlN after hot pressing sintering, we can found that W, Cu diffraction peak intensity was significantly increased, the width narrowed, which indicates W and Cu particle grows up in the sintering process.
Another advantage of this method is that the resulting copper-clad tungsten copper powder can avoid volatilization and subsequent leak in the high-temperature liquid phase sintering process which led to the composition of organizational control are not allowed, to avoid reducing the final product performance.
Because of the poor wettability of the liquidphase copper on the tungsten surface in the ordinary state, the sintering densification process does not occur when the tungsten copper is prepared by the ordinary powder mixing+ shaping+ sintering process.
W40Cu selection of fine tungsten copper tungsten, copper powder,soaked by class sintering process is refined, it can withstand nearly 2,000 high temperature and high stress, high melting point, high hardness, resistance to burning and good adhesion resistance, electrolytic corrosion product surface finish, high precision, low loss.
Studies have pointed out, the manufacture of hard alloy cutting tools must use native tungsten carbide powder,otherwise, holes will appear in the sintering process, and therefore to carry out some quality problems of chipping etc.
Tungsten copper powder metallurgy method is the choice of preparing fine tungsten,copper powder, soaked by the sintering process is refined class, can withstand high temperatures and nearly 2,000 high stress, with high melting point, high hardness, resistance to burning and good anti-adhesion resistance, electrical corrosion product surface finish, high precision, low loss.
The multi-layer sintered metal mesh is a new type of filter material which is made of a multi-layer metal woven wire mesh and is manufactured by a special lamination pressing and vacuum sintering process, and has high mechanical strength and overall rigid structure.
Overall, the production of high-temperature liquid phase sintering process is simple, but has a high sintering temperature, sintering time is long, a large number of volatile copper, poor sintering performance, lower sintered density and other shortcomings, so the high-temperature liquid phase sintering method can not prepare high density of tungsten copper composite material, if after assisted sintering process makes the process complicated and costly.
