顆粒強(qiáng)化耐磨材料的制造方法有哪些?

顆粒強(qiáng)化組織更耐磨

顆粒強(qiáng)化耐磨材料品種繁多,多數(shù)制造過程是將復(fù)合過程與成形過程合為一體,同時(shí)完成復(fù)合和成形。由于基體金屬的熔點(diǎn)、物理、化學(xué)性質(zhì)不同,增強(qiáng)顆粒的化學(xué)、物理性質(zhì)不同,應(yīng)選用不同的制造方法。現(xiàn)有的制造方法有:粉末冶金法、熱壓法、熱等靜壓法、擠壓鑄造法、共噴沉積法、液態(tài)金屬浸滲法、液態(tài)金屬攪拌法、原位反應(yīng)合成法等。上述方法可歸納成三大類:固態(tài)法、液態(tài)金屬法、原位反應(yīng)合成法及其他制備法。
