Time control is answered when 5 is small or so.
A kind of preparation method of Powder metallurgy pressure-resistant composite metal material, first by stainless steel powder, iron powder, titanium, graphene
And chromium, it is uniformly mixed using vacuum mixing apparatus, reuses grinding apparatus, be polishing to 100-300 mesh powder, is added appropriate
Water, mix remaining material, polished again mixed material using grinding apparatus, after the completion of polishing, use drying equipment
Drying operation is carried out to the mixed material of material, under the pressure of 14Mpa, the material after drying is pressed into bulk.
Preferably, in the case of the nitrogen protection, by lump material at a temperature of 800 DEG C, when sintering 7-11 is small, then
It is 300-500 mesh powder by crushing material.
Preferably, it is described to mix pulverized material at a temperature of at least 70 DEG C, 60-100 points of incorporation time scope
Clock, loads grinding tool, is finally pressed into base.
Preferably, it is described by blank under conditions of 900 DEG C sintering 4 it is small when, be cooled to room temperature by material.
Preferably, the grinding apparatus can be the equipment such as ball mill.
Compared with prior art, the beneficial effects of the invention are as follows：The Powder metallurgy pressure-resistant composite metal material and its preparation
Method, the intensity and hardness higher of material structure can be preferably suitable for plurality of devices and device, creative addition titanium
With the material such as manganese, make the scope of application of the material wider；It is more convenient to the process of material, serious forgiveness higher, effectively
Reduce the waste of material, while processing efficiency is more efficient, can be during large batch of application manufactures.
