摘要:

使用電場(chǎng)與流場(chǎng)協(xié)同精整（EFSF）技術(shù)對(duì)鎢試樣進(jìn)行表面拋光。采用金相顯微鏡、表面粗糙度儀、千分尺、光澤度儀、顯微硬度計(jì)分別表征了樣品表面形貌、表面粗糙度、試樣厚度、表面光澤度及表面硬度。結(jié)果表明：EFSF技術(shù)能夠顯著改善鎢的表面品質(zhì)，使其表面粗糙度Ra可以達(dá)到0.154 μm，光澤度達(dá)到223.1 GU，獲得較好的鏡面加工效果。但是EFSF技術(shù)存在表面品質(zhì)改善閾值，當(dāng)粗糙度降低到一定程度（如Ra<0.3 μm）時(shí)，“粗糙度改善/材料損耗”性價(jià)比偏低。同時(shí)，EFSF技術(shù)可以獲得低應(yīng)力且表面硬度穩(wěn)定的高品質(zhì)加工表面，當(dāng)加工時(shí)間>10 min后，表面硬度基本穩(wěn)定在228.4 MPa。EFSF技術(shù)可以實(shí)現(xiàn)對(duì)鎢的高鏡面、低損傷、低應(yīng)力表面拋光，為鎢的高品質(zhì)、綠色表面精整處理提供了一種新選擇。

Abstract:

Synergistic finishing technology of electric field and flow field (EFSF) was used to polish tungsten sample. Surface morphology, surface roughness, sample thickness, surface glossness and surface hardness were analyzed by metallographic microscope, surface roughness meter, micrometer, gloss meter and microhardness tester. The results show that EFSF technology can significantly improve the surface quality of tungsten. It can obtain a high�瞞irror surface with roughness of 0.154 μm and glossness of 223.1 GU.However, EFSF technology has a surface quality improvement threshold. When the roughness is reduced to a certain level (such as Ra<0.3 μm), the cost-effectiveness of “roughness improvement/material loss” is relatively low. At the same time, EFSF technology can obtain a high-quality surface with low stress and stable surface hardness. After processing for >10 minutes, the hardness is basically stable at 228.4 MPa. So EFSF technology can achieve high-mirror, low-damage, low-stress polishing surface of tungsten. This paper provides a new option for high-quality and environmentally friendly surface finishing of tungsten.
