【摘要】:對(duì)基材鋼(1Cr12Mo、X20Cr13、2Cr12Ni Mo1W1V)、C1(長(zhǎng)城1號(hào))涂層、表面處理工藝(6 min與12 min鋼丸強(qiáng)化)三類6種不同氣輪機(jī)葉片材質(zhì)在200~600℃的不同沖角條件下的沖蝕率進(jìn)行了沖蝕實(shí)驗(yàn)。結(jié)果表明:葉片因沖蝕的失重均隨沖蝕顆粒質(zhì)量呈線性變化;15°~25°沖角沖蝕率最大,90°沖蝕率最小;實(shí)驗(yàn)基材的沖蝕率隨實(shí)驗(yàn)溫度提高呈先下降后升高趨勢(shì);2Cr12Ni Mo1W1V在200℃與300℃的沖蝕率高于另兩種材質(zhì),耐沖蝕性差,但在400℃實(shí)驗(yàn)溫度且沖角40°狀態(tài)下沖蝕率低于另兩種材質(zhì);鋼丸強(qiáng)化表面處理工藝對(duì)于提升實(shí)驗(yàn)材質(zhì)抗沖蝕特性無明顯優(yōu)勢(shì);C1涂層的沖蝕率隨溫度升高呈先升高后降低趨勢(shì),在高溫條件下具有良好的抗沖蝕特性。
