| 摘要 |
The present invention relates to methods for finishing wood articles, wherein a metal is deposited according to an electrical-arc metallisation technique onto a previously treated surface so as to form two consecutive layers, i.e. an inner layer and an outer layer. When applying the inner layer, the flow of the metallisation device is directed at an angle of between 30 and 60 DEG relative to the surface, while maintaining the metal at the location where it is brought into contact with the surface at a temperature which is lower than the wood carbonisation temperature but higher than the metal viscous and plastic deformation temperature. The metal used during the application of the inner layer is selected from zinc, tin, lead or alloys thereof. The electrodes of the electrical-arc metallisation device are in the shape of a wire made of identical or different metals or alloys. The ratio between the squared diameters of the electrodes is inversely proportionnal to the ratio between the fusion temperatures of the metals of said electrodes. |
