Ni-Mo/Al composite coatings were obtained by electrodeposition from a Ni-Mo plating bath containing suspended Al particles. The factors including temperature, current density, and stirring rate affecting coating composition, wear, roughness and morphology have been studied. It was found that properties like as hardness, roughness, wear and the deposited Al particle content of coatings show parabolic behavior by changing each parameter. It means that there is a critical value for mentioned parameters in which properties of coatings become maximum.

Automobile safety is the study and practice of design, construction, equipment and regulation to minimize the occurrence and consequences of traffic collisions. Road traffic safety more broadly includes roadway design. Improvements in roadway and automobile designs have steadily reduced injury and death rates in all first world countries. Nevertheless, auto collisions are the leading cause of injury related deaths, an estimated total of 1.2 million in 2004 or 25% of the total from all causes. Of those killed by autos, nearly two-thirds are pedestrians. If any object suddenly comes in front of vehicle the driver might fumble and push accelerator pedal instead of brake pedal.
