New methods of internal combustion engine cylinder surface forming

Abstract

This article comprises a description of methods of internal combustion engine cylinder machining including a description of traditional machining method and a description of some new machining methods – being in use in the motor industry. Special attention has been given to a laser beam treatment method. Results of cylinder surface structure examination after laser-beam treatment with an electron microscopy method and with the use of a scanning microscope have been always presented.

Possibilities to modify the properties of the AW7075 aluminum alloy for the automotive industry

“…In addition, classic methods of surface finishing of engine structures, such as cylinder honing [8], require good machinability and abrasion of the material. All this makes operations modifying the AW7075 alloy, which will give it optimal properties for a given application, become very important.…”
