Researchers have discovered that graphene-based lubricants and coatings can slow down wear damage in mechanical parts used during the cold pilgering process, where tubes of differing alloys are used to reduce the diameter and wall thickness of extrude tube. The researchers found that graphene lubricant slowed down the rate at which the tube walls were damaged by thermal expansion when exposed to a temperature between -80
Researchers have discovered that graphene-based lubricants and coatings can slow down wear damage in mechanical parts used during the cold pilgering process, where tubes of differing alloys are used to reduce the diameter and wall thickness of extrude tube. The researchers, from the Indian Institute of Technology's Department of Metallurgic Engineering and Material Science in Mumbai, in partnership with the Nuclear Fuel Complex's Department of Atomic Energy, found that the graphene-based lubricant notably reduced abrasive wear compared to the mineral oil lubricant and that future industrial applications could be useful in the cold pilgering process, as well as other machinery.
