CHROMIUM AND NICKEL PLATING ALUMINIUM. We have had some Kestrel pistons plated with chromium and with nickel and heating up to 400°C has not produced any tendency to separation of the plating in spite of the difference in expansion. Additionally the plating can be ground without flaking. We propose to run one of these pistons and if satisfactory it would seem worth while considering the possibility of plating an aluminium cylinder block as a means for dispensing with a separate dry steel liner for car engines, thereby saving weight and length. ---------- Hs{Lord Ernest Hives - Chair}/Wd.{Mr Wood/Mr Whitehead} | ||
