Ni本身就具有一定的抗腐性，如對(duì)抗Cl離子的應(yīng)力腐蝕與苛性堿腐蝕具有較好抵抗能力。而鎳基合金中添加的鈍化多種元素可與基材相形成固溶體，提升了材料的腐蝕電位及熱力學(xué)穩(wěn)定性。如Ni中加入 Cu, Cr,Mo等，提高整體合金的耐蝕性 </p> <p> 此外，合金元素能促使合金表面生成致密的腐蝕產(chǎn)物保護(hù)膜，如形成Cr2O3, Al2O3等氧化層，提供材料抵抗各類腐蝕環(huán)境的保護(hù)層，因此鎳基耐蝕合金通常含有Cr、Al這兩種元素之一或兩者都有，尤其是當(dāng)強(qiáng)度不是合金主要要求時(shí)，要特別注意合金的抗高溫氧化性能和熱腐蝕性能，高溫合金的氧化性能隨合金元素含量的不同而有所差異，盡管高溫合金的高溫氧化行為很復(fù)雜，但通常仍以氧化動(dòng)力學(xué)和氧化膜的組成變化來(lái)表示高溫合金的抗氧化能力，在此將純鎳及主要鎳基合金之耐蝕性質(zhì)分述湖北銷售激光熔覆粉末維修價(jià)格鎳基合金粉末不能受潮！</p><div

Creep，在高溫時(shí)為主要機(jī)制。沿晶界擴(kuò)散的叫做Coble Creep，在低溫時(shí) 為主要機(jī)制。因此晶粒越小越容易發(fā)生擴(kuò)散潛變。(3)晶界滑移：因高溫時(shí)晶界較弱，材料易沿晶界產(chǎn)生滑移，造成沿晶裂縫。宏博激光科技提醒您，鎳基合金粉末吸潮了，使用前應(yīng)進(jìn)行干燥處理。</p><div
