style="text-indent:25px">閥門模具在工作中除了要求基體具有足夠高的強(qiáng)度和韌性的合理配合外，其表面性能對(duì)模具的工作性能和使用壽命至關(guān)重要。這些表面性能指：耐磨損性能、耐腐蝕性能、摩擦系數(shù)、疲勞性能等。這些性能的改善，單純依賴基體材料的改進(jìn)和提高是非常有限的，也是不經(jīng)濟(jì)的，而通過表面處理技術(shù)，往往可以收到事半功倍的效果，這也正是表面處理技術(shù)得到迅速發(fā)展的原因。閥門模具的表面處理技術(shù)，是通過表面涂覆、表面改性或復(fù)合處理技術(shù)，改變模具表面的形態(tài)、化學(xué)成分、組織結(jié)構(gòu)和應(yīng)力狀態(tài)，以獲得所需表面性能的系統(tǒng)工程。從表面處理的方式上，又可分為：化學(xué)方法、物理方法、物理化學(xué)方法和機(jī)械方法。雖然旨在提高模具表面性能新的處理技術(shù)不斷涌現(xiàn)，但在模具制造中應(yīng)用較多的主要是滲氮、滲碳和硬化膜沉積。北京**閥門模具批發(fā)</p><p
