Green cutting disc is cutting equipment that isused in many industrial productions today, and now cutting sheets have been
used in new fields. What are these areas? Today, I will introduce you to the
new application areas of the green cutting disc.
1. Application of prealloyed powder in diamond tools
The pre-alloyedpowder has a fairly uniform composition uniformity since each of the powder
particles contains various metal elements constituting the alloy. Since the
eutectic point is much lower than the melting point of the single element in
the alloy, the sintering temperature required for the pre-alloyed powder is low.
(1) atomization method
The pre-alloy powder high-pressureatomization method is to melt the metal of various components into an alloy
before sintering and then atomize thepowder to obtain a carcass powder of the desiredparticle size according to the designed carcass ratio. The atomization method
can be divided into water atomization and gas atomization according to the
atomization medium, and gas atomization can use air such as air, nitrogen or
argon. The gas atomization cooling rate is fast, the powder crystal grains are
fine, the powder yield is high, and the cost is low. Since water is more
viscous than gas and has a high cooling capacity, the water atomization method
is particularly suitable for metals and alloys having a relatively high melting
point.
(2) Coprecipitation method
The coprecipitation method is to add aprecipitant and a surface modifier in a solution containing two or more metal
ions, and to strengthen the process conditions to precipitate various metal
ions at almost the same time to obtain a uniform precipitate, and then The
method in which the precipitate is treated by heat decomposition, reduction,
crushing, sieving, etc., to finally obtain thedesired powder.
