Mechanism of Carbonaceous Deposit Formation Caused by Lubricating Oil on High Temperature Metal Surfaces

While formation of deposits in machinery used under high temperature conditions is inevitable, it needs to be minimized as much as possible. Desorption of deposits, though rarely reported, also needs to be addressed, as it could cause secondary damage. There have been a number of reports on the form...
