1、成分對(duì)合金襯板鋼材料腐蝕條件下沖擊磨損性能與機(jī)理的影響摘要腐蝕條件下的沖擊磨損是濕式磨機(jī)襯板的主要工作環(huán)境。在襯板和磨球的使用過程中，不僅受到磨料的沖擊磨損，而且經(jīng)受漿料的腐蝕。三者的交互作用加劇了材料的磨損。傳統(tǒng)的襯板材料如高錳鋼、中碳合金鋼等綜合性能欠佳。新型低碳高合金襯板鋼的出現(xiàn)彌補(bǔ)了這一缺陷。鎳對(duì)于合金鋼性能的改善是獨(dú)特的。但資源有限，價(jià)格昂貴。本研究通過調(diào)節(jié)合金中鎳的含量，同時(shí)加入適量的錳，在不大幅降低使用性能的前提下，力圖得到具有更高性價(jià)比的合金襯板鋼材料。對(duì)熔煉得到的三種襯板鋼材料進(jìn)行適當(dāng)?shù)臒崽幚恚治鼋M織并測(cè)定
2、其力學(xué)性能和耐腐蝕性能。結(jié)果表明：三種材料的最終組織均為馬氏體組織，綜合性能隨錳含量的增高而降低。三種成分襯板鋼腐蝕條件下的沖擊磨損性能實(shí)驗(yàn)在MLD．10型動(dòng)載磨粒磨損實(shí)驗(yàn)機(jī)上進(jìn)行，選取兩種沖擊功分別進(jìn)行測(cè)試。結(jié)果表明：在本實(shí)驗(yàn)條件下原低碳高合金襯板鋼具有最好的耐腐蝕條件下的沖擊磨損性能，而含鎳1．0％，錳1．5％的合金襯板鋼材料具有最高的性價(jià)比。本文同時(shí)對(duì)三種材料腐蝕條件的沖擊磨損機(jī)理進(jìn)行了探討。關(guān)鍵詞：成分，沖擊磨損，襯板鋼，低碳高合金鋼，磨損機(jī)制EffectofCompositiononImpact-wearBehavi
