Metal is deposited in a vapour deposition process or a spray deposition process employing an apparatus. The apparatus comprises at least one roller arranged for consolidation of the deposited metal by rolling in the course of the deposition process. The roller comprises a plurality of sub-rollers arranged across the span of the roller and disposed from a common support in a manner such that each sub-roller is capable of independent movement in radial directions against the action of a centering bias means. The rollers can conform to the surface contours of the deposit across the span of the roller whilst sufficient force is provided through each sub-roller to flatten asperities and consolidation is produced within the rolled area. |
