二硫化钼在粉末冶金中的应用你知道吗?
来源:http://www.jnjrh.com 日期:2019-10-15 发布人:admin
  二硫化钼粉末冶金是一项新技术、新工艺。北京冶金系统某厂生产了各种二硫化钼粉末冶金产品,如机床摩擦片、机车十字头滑块摩擦片、接触套、密封圈等。
  Molybdenum disulfide powder metallurgy is a new technology and process. A plant of Beijing Metallurgical System has produced various kinds of molybdenum disulfide powder metallurgical products, such as machine tool friction discs, locomotive cross head slider friction discs, contact sleeves, sealing rings, etc.
  式中:87%纯铁粉,石墨,10%,3%二硫化钼(2)二硫化钼(MoS2)初使用内部和外部摩擦块的处理,一层镀镍(约10 ~ 15纳米厚),然后使用上述公式压制好的二硫化钼(监理)粉末冶金材料双面压力钢核心换船(原摩擦盘)、二硫化钼(监理)粉末冶金厚度为1.5毫米。即两侧为二硫化钼(MoS2)粉末冶金,中间为钢芯板。压制成型是在专用模具中进行的,将压制的二硫化钼(MoS2)粉末冶金摩擦片在烧结炉中进行烧结,经过约1000℃的热处理,在烧结过程中通过氧气保护,防止氧化。烧结后的粉末冶金摩擦片与铜芯板牢固粘结。然后,磨两个平面,你可以使用他们。

  Formula: 87% pure iron powder, graphite, 10%, 3% molybdenum disulfide (2) molybdenum disulfide (MoS2) was initially treated with internal and external friction blocks, a layer of nickel plating (about 10-15 nanometers thick), and then used the formula to press the molybdenum disulfide (supervision) powder metallurgical material double-sided pressure steel core ship change (original friction disc), molybdenum disulfide (supervision) powder metallurgical thickness of 1.5 mm. That is, molybdenum disulfide (MoS2) powder metallurgy on both sides and steel core plate in the middle. Compression moulding is carried out in a special die. The compacted MoS2 powder metallurgical friction sheet is sintered in a sintering furnace. After heat treatment at about 1000 C, oxidation is prevented by oxygen protection in the sintering process. The sintered powder metallurgy friction sheet is firmly bonded to the copper core plate. Then, grind two planes, and you can use them.
  (3) MoS2特性:低摩擦系数;2. 2. 高耐磨性;3.良好的导热性和热稳定性;4. 良好的咬合的阻力;5. 可实现无油润滑。
  (3) MoS2 characteristics: low friction coefficient; 2. high wear resistance; 3. good thermal conductivity and thermal stability; 4. good occlusion resistance; 5. oil-free lubrication can be achieved.
