Study of Physicochemical Properties of CoCrMo Alloy with PLCL Polymer Coating Intended for Urology

The paper presents the results of the physicochemical properties test of biodegradable polymer coating on CoCrMo alloy intended for applications in urology. The Co alloy was subjected to grinding, mechanical polishing and chemical passivation and was coated by the dip-coating method with a poly(L,L-lactide-\(\varepsilon \)-caprolactone)—PLCL biodegradable polymer. The paper shows the results of the macroscopic evaluation, study of wettability and surface roughness, potentiodynamic resistance to pitting corrosion in a solution of artificial urine and adhesion test. Based on these results, suitability/usefulness for use in urology of biodegradable PLCL polymer coating on CoCrMo alloy was assessed.
