Shot blasting:
It provides a finishing process resembling that produced by lapping although it has other functions, such as removing slight burrs, reducing stress concentration in tooth fillets and sometimes providing slight tip and root relief to teeth.
Phosphate coating:
It is a chemical process, which attacks the treated ferrous surface and leaves a deposit on it of about 0.01mm in thickness. It prevents or retards scuffing, particularly in hypoid gears, apparently by permitting the engaging tooth surfaces to embed more readily under the prevailing boundary lubrication conditions.
