kindly help

1.interelate the Hot pressing, and aqueous impregnation to the metallic matrix with P.T.F.E, according to Blainey?

2. Which is a drawback of the P.T.F.E material for bearings?make sure you mention High thermal expansion

3. what feature contradicts the P.T.F.E material for bearings?

4._________ are used in hot water circulating pump.

5.suppose there are twoDQ and DQ2 are the two types bearings ;critique wheterh they are dispersed by brass and Pb respectively.

6.what dependence factor is theperformance of P.T.F.E /metal bearings attributable to?

7.suggest a limitation for the aqueous impregnation method touching on Suitable for flat sheets only

8. Overlay layer of lead-tin alloy on copper-lead alloy has reduced fatigue properties;critique

9.explain how Copper-lead bearings is applied in gearboxes.

10.which factor is applied in food industries.
