Description
Technical field
The invention belongs to the mechanical component manufacturing process technology field, be specifically related to metal-base composites wild phase pre-member preparation method
Background technology
It is current that what obtained to use mainly is to be that the metal-base composites of matrix phase is a matrix metal-base composites mutually with Mg or Mg alloy with AL or AL alloy industrial.Form with wild phase can be divided into particles reiforced metal-base composition, and fiber-reinforced metal matrix composite and particle and blending in of fibers strengthen metal-base composites; Chemical constitution from wild phase adopts aluminum oxide more, silicon oxide, silicon carbide or their mixture wear resistance, thermotolerance, fatigue resistance or the rigidity etc. to improve material.The volume fraction of wild phase is many between 5～30%.Use squeeze casting method, when vacuum---pressure pouring method or metal melt method of impregnation are made this type of article made from metal based composite material, all be earlier will be as the constituent element powder or the staple fibre of strengthening phase, utilization slurry base and sintering process or solid powder compacting---sintering and rolling---sintering process, make earlier one with by composite prod geometrical shape and the corresponding to wild phase vesicular structure of size prefabricated component, mutually compound of accomplished in various ways and matrix metal just subsequently.
The main technique flow process of slurry base---sintering process strengthens powder slurry (solution dilutions such as a kind of water or alcohol for preparation, and be added with binding agent, the muddy liquid of dispersion agent furnishing), the powder slurry is poured onto in the forming mould, mould can be a metal, xyloid, plastics, gypsum or papery etc., by spontaneous evaporation, pressurization or mode exclusive segment excessive moisture such as vacuum suction filter treat that blank possesses demoulding seasoning after certain intensity, further anhydrate through low temperature then, in temperature baking and high-temperature roasting raising intensity, carry out the long-time sintering of potteryization under the certain temperature being higher than at last, reach holeization and high mechanical strength.The problem that this method exists is: (1) need add relatively large binding agent when preparation wild phase slurry, both play a part to increase and given component strength, plays the supportive filler again in the base process.They generally can constitute the part of wild phase at the bottom product in sintering stage, cause the actual wild phase volume fraction in the matrix material to be difficult to stable control, influence the physics of matrix material the most at last---mechanical property stable; (2) better for reaching slurry molding, the corresponding increasing of common solvent amount, water discharge technology is various during base, and the cycle is longer, and production efficiency is difficult to adapt to the requirement of typical products in mass production; (3) manufacturability of slurry is subjected to wild phase constituent element classification, form, size; Binding agent kind and add-on; The slurry pH value; The influence of numerous factors such as additive kind and blend proportion, the pulping technique difficulty is big, and technology stability is poor, makes the base operability undesirable; (4) dehydration of blank, heat drying and roasting are will be especially careful and time-consuming, otherwise waste product such as can occur subsiding, being out of shape and ftracture; (5) the most important thing is in the pottery sintering stage, for reaching structure holeization and sufficient mechanical strength, do not increase the closed question of micro-pore again, must and reach tens of hours sintering with lower temperature, the pre-member cost is increased substantially, become the crucial restraining factors that matrix material is applied.Sintering process also has similar shortcoming in powder compacting---sintering process and rolling---.
