Abstract
A process for preparing gradient function material widely used in the fields of aviation, space flight, car engine, and antiwear and anticorrosion includes such technological steps as follows: pre-treated powdered ceramic and fused base metal as raw materials are poured into centrifugal moulding pipe in which the interlayer of foam metal has been loaded. Under the high-speed centrifugal action, the reduction of speed of mass migration and deposition is utilized by the interlayer of foam metal to realize the connection of structural gradient so as to optimize thermostress buffered gradient function material with gradient distribution of structure, composition and performance.
Description
Foam metal intermediate layer legal system is equipped with function-graded material, belongs to the metal-base composites field.
The preparation method of known function-graded material mainly contains chemical vapor deposition (CVD), physical vapour deposition (PVD) (PCD), plasma spraying, laser melting coating, self-propagating high-temperature synthetic (SHS), powder sintered etc., but exist preparation technology's means complexity, cycle long, the properties of product price is than low, apparatus expensive, can not prepare problems such as massive material.The centrifugal casting gradient composites is a kind of short flow process, gradient composites preparation method cheaply, development in recent years is rapid, spontaneous and the artificial gradient composites of centrifugal casting occurred, but in-situ graded composite has determined the narrow of its application surface owing to be subjected to the restriction of material system; And there is defective in artificial gradient composites on its gradient-structure, promptly under centrifugal force field and curing condition, the distribution that two kinds of materials of density contrast are arranged not is the gradient distribution on the complete meaning, can only form comparatively desirable gradient-structure in certain part of its section, when particularly two constituent density contrasts are big, all the more so.
The objective of the invention is to adopt centrifugal force-foam metal intermediate layer method, by foam metal intermediate layer functionally gradient material (FGM) that effect obtains to have complete gradient-structure that slows down to the migration of the second phase ion, deposition in centrifugal force field, the structure of this finished material, composition, performance are complete gradient and distribute, and technological process is simple, can prepare the bulk functionally gradient material (FGM).
The present invention is achieved through the following technical solutions.
Fig. 1 is a process chart of the present invention.
Adopt pretreated ceramic powder particle (aluminium oxide, carborundum, silicon nitride etc.), melting parent metal to do Be raw material, mix in advance, pour into the centrifugal mold pipe that the foam metal intermediate layer is housed and has preheat temperature In, High Rotation Speed, under the seepage flow of centrifugal force and foam metal, the effect adsorbing, stop, liquid metal with Granular pottery by the hole in foam metal intermediate layer permeate, convection current, transposition, utilize in the middle of the foam metal Layer slows down material migration deposition, realizes inside and outside circumference place and near foam metal intermediate layer and Gradient connect, by the control to foam metal intermediate layer and process, obtain complete thermal stress relieve type The material of gradient-structure.
The uniform metal of surface chemical plating (nickel plating or copper) layer is adopted in the preliminary treatment of ceramic powder particle. The foam gold The preparation that belongs to the intermediate layer is to adopt the Pressure-seepage Flow method, carries out in two steps, at first land plaster is made 0.5-2mm's Particle adds 1 gram organic solvent as adhesive, 450-500 ℃ of temperature in every 8-12 gram gypsum sand Lower sintering 2-5 hour, obtain prefabricated section; It is together pre-under 400 ℃ of temperature that second step is put into mould with prefabricated section Heat pours into molten metal liquid, metal is infiltrated in the prefabricated section, last water Gypsum is dissolved away, namely obtain foam metal.
Each operation technical conditions is as follows:
1, ceramic powder particle granularity: 50--200 order
2, raw material preheating temperature: 400-600 ℃;
3, mix mixing speed: 100-300 rev/min
4, cast temperature: greater than parent metal fusing point 20-100 degree;
5, pattern preheat temperature: 0.5-0.8 parent metal fusing point doubly;
6, intermediate layer foam metal: through hole, porosity are 50-80%, aperture 0.1-10mm;
7, centrifuge speed: 1000-2500 rev/min;
The advantage and the good effect that have of the present invention compared with prior art:
1, can obtain the complete functionally gradient material (FGM) of gradient-structure;
The functionally gradient material (FGM) that 2, can prepare bulk;
3, the equipment needed thereby condition is simple, can accomplish scale production.
Embodiment one:
Aluminium oxide powder (100 order) carries out being preheating to 450 degree with crucible after chemical nickel plating on surface is handled, mix with fusion cast aluminium 101 (ZL101) alloy, speed with 100-200 rev/min mixes, the centrifugal pattern that pour into preheating 400 degree, rotates at a high speed, preset the foam copper of porosity 70%, aperture 0.5mm in the centrifugal pattern, the control centrifugal rotational speed is 2000 rev/mins, can obtain the aluminium oxide-foam copper intermediate layer-cast aluminium alloy function-graded material of structural integrity.Embodiment two:
After carborundum powder (150 order) carries out Electroless copper, be preheating to 600 degree with crucible, mix with the fusion basis brass, speed with 100-200 rev/min mixes, the centrifugal pattern that pour into preheating 650 degree, rotates at a high speed, preset the foam copper of porosity 70%, aperture 0.5mm in the centrifugal pattern, the control centrifugal rotational speed is 2000 rev/mins, can obtain the basis brass-foam copper intermediate layer-carborundum function-graded material of structural integrity.
