Layer-by-layer laser remelting (LRM) was used in the technology of laser metal deposition in order to reduce the porosity of the layer in the case of single-layer and multi-layercoatings. The layer porosity is shown to decreases with LRM at a rate 5 times higher than the rate of metal deposition. The dependence of the porosity estimated using the method of the hydrostatic weighing on the rate of laser remelting is obtained.
