Cars corrosion - Essay Example( Shaw Barbara and Kelly Robert, 2006) horizontal though corrosion was still prevalent in the 1950s the main criteria for a car producer was the strength and durability of the body. Cold rolling of low carbon sheets was the accepted practice during those times. Later on, when the reach and features of the simple machinemobile underwent changes steels that were more ductile and could be drawn easily was incorporated into the design. Currently various progress methods of steel fabrication with the use of alternative materials are being followed which are both cheaper and also claim a lower weight to volume ratio. ( Hamilton Bruce and Macauley, 1998)This method of using salt to melt the ice on roads was introduced following World War II which direct to an increase of corrosion, affecting the functional and geomorphological integrity of the vehicle. The general appearance of the vehicle was also affected.
