HARD CHROME PLATING
ADVANTAGE OF HARD CHROME PLATING :
Hard Chrome plating is a very important surface treatment method
for the plastic processing industry.Hard Chrome layers are
precipitated electrochemically from standard or mixed acid
baths.The mixed acid baths used of late have the advantage of a
higher precipitation rate and the disadvantage of being more
aggressive,so that problems may accor in the masking of molds.In
contrast to other surface treatment methods,hard chrome plating is
performed at relatively low temperatures,and the as a consquence
it offers some advantages.
Hardening without distortion
Wear resistance
Surface smoothness
Low coefficient of friction
Little tendency for materials to adhere
Resistance to chemical environments
Corrosion resistance
No oxidation at elevated temperature
FACTORS AFFECTING THE PROPERTIES OF CHROME
SURFACE LAYERS(CHEMICAL AND ELECTROCHEMICAL ).
To achieve all the desired properties,hoever,a great deal of
experience is necessary.Factors influencing the properties of the
chrome layer.
MATERIAL : Analysis ,Method of production,Surface quality.
CONDITIONING : Surface
machining,Cleaning,Degreasing ,Activating.
TREATMENT : System used,Treatment bath,Precipitation
conditions.
FINISHING : Mechanical treatment,Heat treatment.
Its clear that great importance must be attached to the base
material to be hard chrome plated.It should exhibit a relatively high
of hardness in order to provide adequate support,as otherwise
flaking may occur under high specific loads because of the
