| titleOfInvention | A kind of B2 type NiAl based self lubricated composite material and preparation method thereof |
| abstract | The invention provides a kind of B2 type NiAl based self lubricated composite material and preparation method thereof.The method comprises the steps: 1) choose Ni powder, Al powder, Mo powder, Nb powder, nano-graphene and WS by proportioningn 2 powder, is prepared burden; 2) above-mentioned batching be placed in vibrator and dry grind, vibratory milling top tank structure is polytetrafluoroethylene (PTFE), and vibration frequency is 45Hz, and amplitude is 5mm, and vibration force is 10000N, and duration of oscillation is 30-50 minute, obtains the mixed-powder that pretreatment is good; 3) mixed-powder that pretreatment is good is placed in the graphite jig that interior diameter is 20mm, then under vacuum condition, takes discharge plasma sintering method to obtain the aluminium base self-lubricating composite of described B2 type nickel.The self-lubricating composite purity that the method prepares is high, compactness good, and has excellent tribological property.In addition, the discharge plasma sintering method that the present invention takes reduces sintering temperature, shortens sintering time, and step method is simple and convenient, is applicable to scale batch production. |
