Tribology and Surface Engineering

Tribology: Tribology is the wisdom and engineering of interacting shells in relative stir. It includes the study and operation of the principles of disunion, lubrication and wear. Tribology is largely interdisciplinary, drawing on numerous academic fields, including drugs, chemistry, accoutrements wisdom, mathematics, biology and engineering. People who work in the field of tribology are appertained to as tribologists.

The abecedarian objects of study in tribology are tribosystems, which are physical systems of reaching shells. In oiled tribosystems, contact stress can produce tribofilms. Subfields of tribology include memoir tribology, Nano tribology, space tribology and tribotronics.

Components of tribology:

  • Sliding-contact
  • Rolling-contact bearings
  • Seals
  • Gears
  • Cams
  • Tappets
  • Piston rings
  • Electrical brushes
  • Cutting Forming tools

Tribological properties:

  • Friction
  • Wear
  • Lubrication of interacting surfaces

Surface engineering: Surface engineering refers to a wide range of technologies designed to modify the face parcels of metallic and non-metallic factors for ornamental and/ or functional purposes. exemplifications include perfecting erosion and wear resistance to extend element life; making particulars more visually seductive; and giving special parcels similar as lubricity improvement, non-stick shells

Types of surface engineering:

  • Electroplating
  • Anodizing
  • Surface hardening
  • Carburizing
  • Nitriding
  • Thermal spraying
  • Chemical vapour deposition
  • Physical vapors deposition
