Abstract
For obtain nanostructured surfaces on various materials the method of laser deposition of metals from solutions (LDMS) was used. As a solution were used nanosystems: oxide copper (CuO) and a two-component solution of nickel (Ni) and carbon nanotubes. Deposition occurred action of pulse-periodic laser radiation (a wave length 1.06 microns, a pulse length 100ns, a repetition rate of impulses 20 kHz) various power. Laser radiation was focalized on a substrate from a quartz glass and copper. Obtain samples were research on a raster-type electronic microscope (Quanta 200/3D) and an atomic-force microscope (Ntegra Aura). As a result deposition occurred only on a trajectory of a motion of a beam. Deposition layers has good adhesion to a substrate surface. <<The soft mode>> actions of laser radiation as the substrate surface is not exposed to thermal action. The layer roughness made 270nm at height of a relief about 2 microns. The offered method of deposition of metals from the colloid solutions by means of laser radiation is simple, inexpensive, and to substrates scaled to the big areas and length of the precipitated layer.
