“…The various critical components of automobiles where mechanical interaction between two surfaces leads to wear, investigated by TLA technique, are cylinder housing, piston ring, cam follower, valve seat, fuel injection equipment, gear box, brake, etc. The development of better lubricants and additives is tested routinely by setting up of test bench at several accelerator based laboratories [12]. TLA technique has also been applied in armament, aeronautic and space industries and in many other areas [1,3,[14][15][16][17].…”
