Abstract: Thermal spray coating obtained from a thermal spray powder material containing at least one of Aluminum-containing particles, Magnesium-containing particles, and Titanium-containing particles mechanically alloyed to a transition metal. The coating includes Aluminum, Magnesium, or Titanium alloy portions alloyed to the transition metal. The thermal spray powder is obtained of Aluminum, Magnesium, or Titanium containing particles mechanically alloyed to a transition metal.
Abstract: A refrigerating machine oil containing: a lubricating base oil; and a polymer additive, wherein a carbon residue of 10% residual oil is 0.05% by mass or more.
Abstract: Provided is a lubricating oil composition including a lubricating oil additive and a lubricating oil, the lubricating oil additive having nanodiamonds, of which a surface is hydrophobically modified by a surface treatment, dispersed in a base oil. The lubricating oil composition retains dispersibility over a long period of time and thus can ensure storage stability. Machines to which the lubricating oil composition is applied may have improved abrasion resistance as well as improved fuel consumption and reduced noise, and high thermal conductivity of the lubricating oil composition may also increase cooling efficiency and the service life of machines.
