●硼、硅元素的效果：明顯降低合金熔點(diǎn)，擴(kuò)展固液相線溫度區(qū)，構(gòu)成低熔共晶體；脫氧復(fù)原效果和造渣功用；對涂層的硬化、強(qiáng)化效果；改善操作工藝功能 </p> <p> ●銅元素的效果：進(jìn)步對非氧化性酸的耐蝕性 </p> <p> ●鉻元素的效果：固溶強(qiáng)化效果、鈍化效果；進(jìn)步耐蝕功能和抗高溫氧化功能；充裕的鉻輕易與碳、硼構(gòu)成碳化鉻、硼化鉻硬質(zhì)相然后進(jìn)步合金硬度和耐磨性 </p> <p> ●鉬元素的效果：原子半徑大，固溶后使晶格發(fā)作大的畸變，明顯強(qiáng)化合金基體，進(jìn)步基體的高溫強(qiáng)度和紅硬性；可以割斷、降低涂層中的網(wǎng)狀組織；進(jìn)步抗氣蝕、沖蝕才能。 </p> <p> <br /> </p><p style="text-indent:25px">此外，含Cr鎳基合金經(jīng)400~800oC 之熱履歷時(shí)，碳化鉻(M23C6)會析出于晶界，造成晶界周圍形成鉻缺乏區(qū) (Cr-depletion Zone)，而導(dǎo)致此區(qū)耐蝕性降低，稱為敏化而容易導(dǎo)致沿晶侵蝕(IGA)及沿晶應(yīng)力腐蝕破裂(IGSCC)的發(fā)生。另一方面，沃斯田鐵系析出強(qiáng)化鎳基合金之熱處理則包括 (1)升溫至析出物回溶之溫度之固溶階段以及(2)于γ/ γ'兩相區(qū)持溫之時(shí)效階段。其中固溶使得析出物回溶，基地中 γ' 析出所需元素增加，并達(dá)成各添加元素之均質(zhì)化，且控制基材 γ 相之晶粒尺寸；而時(shí)效階段則可以持溫溫度、時(shí)間、冷速與多階段時(shí)效來控制 γ' 之體積分率、形貌、尺寸與分布，主要析出物之分布與形貌可影響潛變與耐蝕性質(zhì)。一般而言，強(qiáng)化相常為奈米尺度，以一般金相方法觀察不易。常須藉助倍率較高之穿透式電子顯微鏡(TEM)來掌握析出物形貌。安陽宏博激光科技有限公司產(chǎn)品鎳基合金粉末。</p><div style="width:100%;text-align: center;"><img

(1)固溶強(qiáng)化元素，藉由此類原子半徑與基材的不同，在Ni-Fe之基地造成局部晶格應(yīng)變來強(qiáng)化材料； </p> <p> <br /> </p> <p> (2)析出強(qiáng)化元素則如Al、Ti、Nb和Ta等，可以形成整合性有序的A3B型金屬間化合物，如Ni3(Al,Ti)等強(qiáng)化相(γ’)，使合金得到有效的強(qiáng)化，獲得比鐵基高溫合金和鈷基合金更高的高溫強(qiáng)度； </p> <p> <br /> </p> <p> (3)晶界強(qiáng)化元素，一般鎳基合金的牌號由其所開發(fā)廠家來命名，如Ni-Cu合金又稱為Monel合金，常見如Monel 400、K-500等。Ni-Cr合金一般稱為 Inconel合金，也就是常見之鎳基耐熱合金，主要在氧化性介質(zhì)條件下使用若是Inconel合金中加入較高量的Fe來取代Ni，則為Incoloy合金，其耐高溫程度不如鎳基析出硬化型合金，但價(jià)格便宜，可用于噴射引擎里溫度較低部份的組件及石化廠反應(yīng)器等，如Incoloy 800H、825等。若于Inconel與Incoloy中加入析出強(qiáng)化元素，如Ti、Al、Nb等，則成為析出硬化型(鐵)鎳基合金，可于高溫下仍保有良好的機(jī)械強(qiáng)度與抗蝕性，多用于噴射引擎的組件，如 Inconel 718 、Incoloy A-286 等。而 Ni-Cr-Mo(-W)(-Cu) 合金則稱為哈氏耐蝕合（Hastelloy)，其中Ni-Cr-Mo主要在還原性介質(zhì)腐蝕的條件下使用。Hastelloy的**牌號如C-276、C-2000等 </p> <p> <br /> 江西口碑好激光熔覆粉末哪里有</p><p
