Glossary
(1) Engineering
the speed at which a manufacturing step is carried out
Rate process:
Transfer process:
a manufacturing process which takes laboratory tastes and
applies them to a practical application.
Hydraulics:
a branch of science that deals with practical applications of
water in motion.
Annealing:
make materials tough by cooling them slowly e.g. glass
(ανόπτηση)
Anodize:
to coat a metallic surface with a protective oxide (car
components) ανοδίωση
Electroplate:
to cover with a thin layer of metal using electrolysis e.g.
car components. (Επιμεταλλώνω δια ηλεκτρισμούεπικαλύπτω).
Forge:
shape metals by heating and then hammering e.g. horse
shoes (επεξεργάζομαι μέταλλο -forged σφυρήλατος)
Found:
to melt metal and then pour it into a form e.g. iron
components. ( τήκω- χύνω μέταλλο)
Galvanize:
to protect from rusting by coating in zinc e.g. food cans
Grind:
to polish or sharpen by rubbing on a rough surface e.g.
stone
Harden:
to make a material strong e.g. steel (βάφω χάλυβα)
Mint:
to make a metal piece by stamping e.g. coins
Plate:
(επιμεταλλώνω ) to cover one metal with a thin layer of
another e.g. silver plate
Roll:
to make flat by pressure applied by a roller e.g. make thin
sheets of steel by passing it between large
rollers(κυλίνδρωση)
Soften:
to make sth softer e.g. fibres(μαλακώνω)
Temper:
to heat and then cool metals to obtain the required
hardness and elasticity e.g. steel (ανόπτηση, βάψιμο
μετάλλου, σκλήρυνση)
Tinplate:
to cover a metal with a thin layer of tin e.g. food cans
Petrochemical:
a chemical derived from petroleum or natural gas
