Nickel-Based Composition Coating with Titanium Nanoboride

Abstract:

Conditions of electrodeposition, the structure and physical-mechanical properties (microhardness, base cohesion, internal stresses, corrosion currents) of nickel-based galvanic composition coatings with nano and micropowders of titanium boride are investigated. It is determined that electrocrystallization of nickel in the presence of boride nanoparticles leads to the formation of coatings with small-sized structural fragments, low porosity and increased physical-mechanical properties. Titanium nanoboride is simultaneously a component of the composition coating and an effective modifier of the nickel matrix. The presence of nanoboride in the electrolyte improves its performance by increasing the allowable upper limit of the cathode current density.
