Abstract
Wear in the boundary lubrication region with an aluminum-steel system lubricated with both alcohols and with aliphatic ethers was investigated under conditions of pure sliding. A pin and cylinder wear machine which provided a continuous record of wear as well as friction and metal-to-metal contact was used for the measurements. It was found that these materials react with the aluminum surface when sliding occurs and the wear mechanism is largely chemical. Higher wear rates are obtained when lubricating with alcohols than are obtained with the aliphatic ethers. Octadecanol produces a much higher wear rate than the other alcohols investigated, probably because of the lower melting point of the octadecanoL-aluminum reaction product.
