連云港優質閥板哪家好無論是機械部件還是金屬部件，突出的問題是表面磨損或腐蝕，或者兩者兼而有之。下面簡要介紹涂層應用指南：1.耐磨-高溫和低溫連云港閥板技(ji)術的應(ying)用領域。這些涂(tu)(tu)層(ceng)可分為以下幾類：(1)抗粘(zhan)著磨(mo)損或(huo)劃痕(hen)-當兩個(ge)表面(mian)相對滑動，碎片(pian)從一個(ge)表面(mian)向另(ling)一個(ge)表面(mian)滑動時，就會產生粘(zhan)著磨(mo)損或(huo)劃痕(hen)。典型的涂(tu)(tu)層(ceng)是(shi)鈷(gu)(gu)基碳(tan)化鎢、鎳(nie)鉻/鉻碳(tan)化物涂(tu)(tu)層(ceng)。(2)磨(mo)料磨(mo)損-磨(mo)粒磨(mo)損發(fa)生在較軟的表面(mian)上(shang)，兩面(mian)之(zhi)間有(you)磨(mo)損。纖維和絲線高速穿過表面(mian)時也會發(fa)生磨(mo)粒磨(mo)損。專有(you)的典型涂(tu)(tu)層(ceng)是(shi)鈷(gu)(gu)基鎳(nie)鉻合金(jin)(jin)、自(zi)熔合金(jin)(jin)混合鉬、氧化鉻涂(tu)(tu)層(ceng)。
