<br /> </p> <p> 熱噴涂技術(shù)在產(chǎn)品加工機械，環(huán)形模是壓制機的關(guān)鍵零件，使用工況要求環(huán)模孔應(yīng)具有較高精度，當(dāng)磨損量大于0.2～0.3 mm時必須報廢。錘片是粉碎機的主要粉碎部件，越靠近前列的線速度越大，與物料的作用頻數(shù)也越大，因此錘片前列嚴(yán)重磨損，導(dǎo)致粉碎效率下降。為了提高錘片前列的耐磨性，在65Mn鋼錘片表面噴焊NiWC合金耐磨層，研究表明，表面處理后錘片壽命的可提高6倍以上。采用熱噴涂工藝，在低溫榨螺表面制備WC-12%Co耐磨涂層。研究表明，WC-12%Co耐磨涂層壽命是傳統(tǒng)滲碳淬火層的4.2倍。擠出機的送料螺桿主要使用38CrMoAl材料制造，加工后經(jīng)氮化處理提高表面硬度和耐磨性。但是在生產(chǎn)中，氮化層容易磨損，造成送料螺桿壽命較低。通過優(yōu)化氧-乙炔火焰噴焊工藝，選擇合適的自熔合金材料，在螺旋送料桿表面制備性能較好的噴焊層，取得了良好的應(yīng)用效果。
