Abstract: A method involves the coating of a metallic substrate with a blasting medium through sandblasting or equivalent techniques. The blasting medium is preferably a powder made of silicon nitride (or other ceramic or engineering materials). The sandblasting process allows the silicon nitride powder to form a loosely packed layer on the substrate. With additional treatment via rolling and/or sliding action against a secondary body in the presence of a liquid lubricant, the loosely packed particle layer turns into a flattened surface matrix consisting of particle clusters and irregular cavities. The silicon nitride particles are spontaneously attached to the substrate surface without the use of an adhesive agent which subsequently leads to the formation of a surface matrix exhibiting a chaotic hybrid topography with zero tensile stress when subjected to rolling/sliding contact pressure. This cluster-cavity matrix can evolve continuously (thus dynamic) and is immune to debris indentation from dirty lubricants.

Abstract: An engagement operation of a dog clutch is carried out while an engagement operation of a second clutch is being carried out, that is, during a situation that an uplock is hard to occur because of a phase shift generated between meshing counterpart members of the dog clutch.

Thus, when the dog clutch is in a non-engaged state at the time of an N-to-D shift during a stop of the vehicle, it is possible to ensure the startability of the vehicle.
