Abstract
In order to metallise a support made from high temperature polymer, the melting temperature of which is higher than 180° C., it is shown that the stages of cleaning, plasma etching, grafting and then metallising in a metallisation bath can be applied. According to the invention, the metallisation bath is brought to a temperature between 50° C. and 70° C., the plasma being a nitrogenous plasma.
Claims13
A plastic part at least partially coated with a metallic deposit including:
- a first non-metallised plastic material,
- a second plastic material at least partially coated by the metallic deposit, characterised in that:
- the metallic deposition includes attachment sites including nitrogenous moieties and palladium moieties at the interface with the second material, includes a first layer, called the initial layer having a first thickness, includes at least one second layer, called the external layer having a second thickness,
- the first and second plastic materials being devoid of metallic or catalytic charges.
