将钨粉和硒粉按物质的量比为1∶2.2混合并球磨后,再在600~800℃进行固相烧结合成了纳米 WSe2,对其微观形貌进行表征;然后将在600℃合成的 WSe2纳米棒作为润滑油添加剂加入到 HVI500基础油中,研究了它的摩擦学性能.结果表明:在700,800℃合成的纳米 WSe2为片状,在600℃合成的纳米 WSe2为棒状,该纳米棒的直径约为500 nm,长约为800 nm;与HVI500基础油相比,2%WSe2纳米棒+HVI500基础油的摩擦因数约降低了40%,具有较好的减摩作用.
將鎢粉和硒粉按物質的量比為1∶2.2混閤併毬磨後,再在600~800℃進行固相燒結閤成瞭納米 WSe2,對其微觀形貌進行錶徵;然後將在600℃閤成的 WSe2納米棒作為潤滑油添加劑加入到 HVI500基礎油中,研究瞭它的摩抆學性能.結果錶明:在700,800℃閤成的納米 WSe2為片狀,在600℃閤成的納米 WSe2為棒狀,該納米棒的直徑約為500 nm,長約為800 nm;與HVI500基礎油相比,2%WSe2納米棒+HVI500基礎油的摩抆因數約降低瞭40%,具有較好的減摩作用.

W and Se powders were mixed and ball-milled with the molar ratio of W to Se of 1∶2 .2 ,and then nano-WSe2 was synthesized by solid state sintering at 600 - 800 ℃.The morphology of nano-WSe2 was characterized.Some WSe2 nanorods sythesized at 600 ℃ were adding to HVI500 oil to study its tribological properties.The results show that WSe2 sythesized at 700 ℃ and 800℃ exhibited flat and WSe2 nanorods with diameters of about 500 nm and lengths of about 800 nm were synthesized at 600 ℃.Compared with HVI500 oil,the friction coefficient of the HVI500 oil containing 2wt% WSe2 nanorods reduced by 40% or so,and the lubricant had relactivey good friction reduction ability.
