摘要

Smoothing a damaged outer surface (20), which is an outer layer of a thermoplastic polymer (21) of a component having optical properties and the thermoplastic polymer has a flow temperature and a glass transition temperature, comprises heating the outer surface such that the temperature of the outer surface is less than the flow temperature and greater than the glass transition temperature of the thermoplastic polymer. The heating takes place by an atmospheric plasma device (10) comprising a clamping device (11) for attachment of the component and comprises an atmospheric plasma apparatus. Smoothing a damaged outer surface (20), which is an outer layer of a thermoplastic polymer (21) of a component having optical properties and the thermoplastic polymer has a flow temperature and a glass transition temperature, comprises heating the outer surface such that the temperature of the outer surface is less than the flow temperature and greater than the glass transition temperature of the thermoplastic polymer. The heating takes place by an atmospheric plasma device (10) comprising a clamping device (11) for attachment of the component and comprises an atmospheric plasma apparatus. The atmospheric plasma apparatus has a plasma nozzle (13) for generating a plasma jet of an ionization gas. The atmospheric plasma apparatus with the plasma jet and the clamping device moved with the thermoplastic polymer, with predetermined machining parameters comprising: a predetermined distance of the plasma nozzle to the outer surface (20), a predetermined speed of the relative movement and predetermined directions of the relative movements. The heat treatment by atmospheric plasma apparatus is carried out without a reaction gas. An independent claim is also included for an atmospheric plasma device for smoothing a damaged outer surface.
