    摘要:

    以稻殼熱解產(chǎn)物為SiO2源,通過(guò)粉末冶金法制備了Si和O固溶強(qiáng)化的低成本鈦合金,并從磨損率、磨損表面形貌和磨屑成分等角度系統(tǒng)研究了其摩擦學(xué)性能和磨損機(jī)理。結(jié)果表明,隨著SiO2加入量的增加,Ti合金的體積磨損率顯著降低,與硬度的變化規(guī)律吻合良好,同時(shí)磨損表面有三處變化,即犁溝的深度變淺、塑性變形程度降低和磨屑的尺寸變小和數(shù)量減少。SiO2的加入使磨損機(jī)制從純Ti的粘著和磨料磨損轉(zhuǎn)變?yōu)槟チ虾脱趸p,而磨屑尺寸的減小可歸因于GCr15球和鈦基體反復(fù)摩擦,導(dǎo)致磨屑的脆化。本文提供了一種使用農(nóng)業(yè)廢稻殼生產(chǎn)具有優(yōu)良綜合性能的鈦合金方法,在降低鈦合金成本的同時(shí)也有益于生態(tài)環(huán)境的保護(hù)。

    Abstract:

    Wear performance and mechanism of Ti alloys strengthened by solid solute atoms Si and O from rice husk was studied from the viewpoint of wear rate, worn surface morphology and wear debris analysis. Results show that the volume wear rate of Ti alloys decreases significantly with the increase of the content of SiO2, agreeing well with the change law of hardness. There are three changes of the worn surface with the increase of SiO2 content, one is the deep grooves transferring to shallow scratches, second is the decrease of plastic deformation degree and the last one is the size and amount of adhesive debris. The decrease of debris size can be attributed to the embrittlement of wear dust due to the blending of the wear dust of counter grinding GCr15 ball as well as the Ti matrix itself. Wear mechanism also transfers from adhesive and abrasive wear of pure Ti to abrasive and oxidation wear with the increase of SiO2 content. The result of this paper provides a cheap method to produce Ti alloys with excellent combination properties by using agricultural waste rice husk, which is also benefit for the environmental protection.
