精密(mi)零(ling)部件的表面處理(li)工藝
精密零部件在(zai)實際的工(gong)(gong)(gong)作中對強(qiang)度和韌性(xing)要(yao)求(qiu)比(bi)較(jiao)高，它的工(gong)(gong)(gong)作性(xing)能與使用(yong)壽命與其表(biao)面(mian)性(xing)能有(you)著(zhu)莫大(da)的聯系，而表(biao)面(mian)性(xing)能的提升，是(shi)(shi)無法單純的依靠材料做(zuo)到的，也是(shi)(shi)非(fei)常(chang)不經(jing)濟的做(zuo)法，但(dan)實際加(jia)工(gong)(gong)(gong)中卻必須使其性(xing)能達(da)到標(biao)準，這時候(hou)就需要(yao)用(yong)到表(biao)面(mian)處理技術了，這往往能達(da)到事半(ban)功倍的效(xiao)果(guo)，近(jin)年來(lai)這項技術也得到了飛速的發展。在(zai)模具表(biao)面(mian)處理優先域模具拋光技術是(shi)(shi)非(fei)常(chang)重要(yao)的環節，也是(shi)(shi)工(gong)(gong)(gong)件加(jia)工(gong)(gong)(gong)處理過(guo)(guo)程中的重要(yao)工(gong)(gong)(gong)藝。精密零部件的表(biao)面(mian)處理工(gong)(gong)(gong)藝在(zai)加(jia)工(gong)(gong)(gong)過(guo)(guo)程中是(shi)(shi)非(fei)常(chang)重要(yao)的，那么精密零部件的表(biao)面(mian)處理工(gong)(gong)(gong)藝有(you)哪些呢？
值(zhi)得提(ti)醒的(de)(de)是(shi)，精(jing)密(mi)零(ling)部(bu)件的(de)(de)模(mo)具表(biao)面(mian)拋(pao)(pao)光(guang)處理工(gong)作，不僅僅只收到工(gong)藝工(gong)序和拋(pao)(pao)光(guang)設備的(de)(de)影響(xiang)，同時還會(hui)受(shou)到零(ling)件材料(liao)鏡面(mian)度的(de)(de)影響(xiang)，這一點在現(xian)在的(de)(de)加(jia)工(gong)中并(bing)沒有得到足夠的(de)(de)重(zhong)視(shi)，這也是(shi)說(shuo)明，拋(pao)(pao)光(guang)本身(shen)就受(shou)到材料(liao)的(de)(de)影響(xiang)。雖(sui)然現(xian)在提(ti)高精(jing)密(mi)零(ling)件表(biao)面(mian)性能的(de)(de)加(jia)工(gong)技術(shu)不斷的(de)(de)革新升級，但是(shi)在精(jing)密(mi)零(ling)部(bu)件加(jia)工(gong)中應(ying)用的(de)(de)比較多的(de)(de)還是(shi)主要為硬化(hua)膜(mo)沉(chen)積，和滲氮(dan)，滲碳技術(shu)。
因(yin)為滲(shen)氮(dan)技(ji)術能夠(gou)獲得(de)很高水準的(de)(de)表面(mian)性(xing)能，而且滲(shen)氮(dan)技(ji)術的(de)(de)工(gong)藝跟精密零(ling)部(bu)件中鋼的(de)(de)淬(cui)火工(gong)藝有著非(fei)(fei)常高的(de)(de)協(xie)調一(yi)致性(xing)，而且滲(shen)氮(dan)的(de)(de)溫(wen)度(du)是非(fei)(fei)常低的(de)(de)，這樣在經過滲(shen)氮(dan)技(ji)術處理后就(jiu)并(bing)不需要激烈的(de)(de)冷(leng)卻(que)工(gong)序，因(yin)此精密零(ling)部(bu)件的(de)(de)變形(xing)就(jiu)會非(fei)(fei)常小，因(yin)而滲(shen)氮(dan)技(ji)術也是在精密零(ling)部(bu)件加工(gong)時用來強化表面(mian)性(xing)能采用最早的(de)(de)技(ji)術之一(yi)，也是目前應用比較廣泛

The surface treatment technology of precision parts and components requires high strength and toughness in actual work, and its working performance and service life are greatly related to its surface performance, while the surface performance is improved It is not possible to rely solely on materials, and it is also a very uneconomic practice, but in actual processing it is necessary to make its performance up to standard. At this point, surface treatment technology is needed, which can often achieve twice the result with half the effort The technology has also developed rapidly in recent years. In the field of mold surface treatment, mold polishing technology is a very important link, but also an important process of workpiece processing. The surface treatment technology of precision parts is very important in the process of machining, so what are the surface treatment technology of precision parts? It is worth reminding that the surface polishing of precision parts is not only affected by the process and polishing equipment, but also by the specular surface of the parts This point in the current processing has not been enough attention, which is to say, polishing itself is affected by the material. Although the machining technology to improve the surface performance of precision parts is constantly upgraded, but the most widely used in precision parts processing is mainly hardening film deposition, and nitriding, carburizing technology. Because nitriding technology can achieve a very high level of surface properties, and nitriding technology and precision parts of the steel quenching process has a very high consistency, and nitriding temperature is very low, after the nitriding treatment, no drastic cooling process is required, so the deformation of the precision parts will be very small Therefore, nitriding technology is one of the earliest technologies used to enhance the surface properties of precision parts, and is also the most widely used at present
