</p> <p> <span

<span style="font-size:16px;">特點(diǎn)：成本低，防腐蝕一般，顏色為銀白色。</span> </p> <p> <span style="font-size:16px;">應(yīng)用：螺絲釘、斷路器、工業(yè)用品等。</span> </p> <p> <br /> </p> <p> <span

style="font-size:16px;">特點(diǎn)：鍍鉻有兩種，第一種是起裝飾作用，外表光亮、耐磨擦性能較好，防銹能力不如鍍鋅，優(yōu)于氧化；第二種是增加金屬零件的硬度、耐磨性等，這是零件的功能性。</span> </p> <p> <span style="font-size:16px;">應(yīng)用：家電、電子等產(chǎn)品上的的光亮裝飾件，水龍頭等。</span>

style="font-size:16px;">鍍鋅鋼一般是在低碳鋼外鍍一層鋅，鍍鋅層一般在20um厚。鋅的熔點(diǎn)在419°C，沸點(diǎn)908°C左右。在焊接中，鋅熔化成液體浮在熔池表面或在焊縫根部位置。鋅在鐵中具有較大固溶度，鋅液體會(huì)沿晶界深入浸蝕焊縫金屬，低熔點(diǎn)鋅形成“液體金屬脆化”。</span> </p> <p> <br /> </p> <p> <br /> </p> <p> <span style="font-size:16px;">同時(shí)，鋅與鐵可形成金屬間脆性化合物，這些脆性相使焊縫金屬塑性降低，在拉應(yīng)力作用下而產(chǎn)生裂紋。如果焊接角焊縫，尤其是T形接頭的角焊縫容易產(chǎn)生穿透裂紋。鍍鋅鋼焊接時(shí)，坡口表面及邊緣處的鋅層，在電弧熱作用下，產(chǎn)生氧化、熔化、蒸發(fā)以至揮發(fā)出白色煙塵和蒸汽，極易引起焊縫氣孔。</span> </p> <p> <br /> </p> <p> <br /> </p> <p> <span style="font-size:16px;">由于氧化而形成的ZnO，其熔點(diǎn)較高，約1800°C以上，若在焊接過(guò)程中參數(shù)偏小，將引起ZnO夾渣，同時(shí)。由于Zn成為脫氧劑。產(chǎn)生FeO-MnO或FeO-MnO-SiO2低熔點(diǎn)氧化物夾渣。其次，由于鋅的蒸發(fā)，揮發(fā)出大量的白色煙塵，對(duì)人體有刺激、傷害作用，因此，必須把焊接處的鍍鋅層打磨處理掉。</span>

style="font-size:16px;">2、持久耐用：在郊區(qū)環(huán)境下，標(biāo)準(zhǔn)的熱鍍鋅防銹厚度可保持50年以上而不必修補(bǔ)；在市區(qū)或近海區(qū)域，標(biāo)準(zhǔn)的熱鍍鋅防銹層則可保持20年而不必修補(bǔ)；</span> </p> <p> <br /> </p> <p> <span style="font-size:16px;">3、可靠性好：鍍鋅層與鋼材間是冶金結(jié)合，成為鋼表面的一部份，因此鍍層的持久性較為可靠；</span> </p> <p> <br /> </p> <p> <span style="font-size:16px;">4、鍍層的韌性強(qiáng)：鍍鋅層形成一種特別的冶金結(jié)構(gòu)，這種結(jié)構(gòu)能承受在運(yùn)送及使用時(shí)受到機(jī)械損傷；</span> </p> <p> <br /> </p> <p> <span
