TEMPERATURE ON CORROSION OF CERMETS ALLOY ABSTRACT Tungsten carbides (WC) are widely used as wear resistant components such as seal‚ valves‚ rings‚ nozzle and bearings. But in some processing operations‚ the environment necessarily includes severe corrosion or extremes of temperatures. In this research‚ commercially cobalt tungsten carbide (WC-6%Co) and nickel tungsten carbide (WC-9%Ni) was examined in seawater (3.5% salinity) to know the effect of temperature on corrosion for both of this

This however didn’t happen due to his brother‚ Richard duke of Gloucester wanting the power; Edward changed his will on his death bed so his wishes weren’t clear; his marriage to Elizabeth Woodville.

a) Conditions under which corrosion is accelerated‚ and b) Methods of preventing corrosion. Two experiments were implemented to answer these questions and hence reach a definate conclusion.First off let’s look at the background of corrosion and the way in which it occurs.The first hypothesis to answer was‚ ’What affect does water temperature have on the rate of corrosion of iron in sea water?’ The assumed answer was that ’ As temperature decreases‚ the rate of corrosion will decrease.’ Secondly‚

Shakespeare: Richard III Shakespeare successfully portrays (his purpose in relation to the values and expectations of the Elizabethan context) through stage play techniques such as‚ use of soliloquy‚ dramatic irony‚ and humour. He also uses language techniques such as visual imagery and sound imagery throughout his play to explore the villainous role and character of Richard which leads to the development of the key themes in his play‚ Richard III. The first soliloquy informs the audience of Richard’s
