Wood substrate with metal coating layers

摘要

A process for forming a coated wood substrate 50 comprises the steps of (i) abrading a surface of the wood substrate 13 , (ii) applying a base coating 21 including a first metal to the abraded surface, (iii) applying a further coating 22 including a second metal over the base coating, and (iv) subjecting the coated substrate to a finishing process. Preferably, the abrading step produces an enhanced three-dimensional grain profile defined by a series of peaks 17 and troughs 18. The finishing process preferably removes some of the further coating layer 22 to expose some of the base coating 21 to produce a two-tone effect. In another aspect, all of the metal coating can be removed to expose bare wood between coated metal areas (figure 9). In further aspects, coating natural wood artifacts such as logs, or wooden or non-wooden substrates with undulations, with a metal layer is disclosed.
