Reference number : GC-2017-Q4-01991, amendment number : , agreement type : G, recipient legal name : Zhitomirsky, Igor (McMaster University), recipient country : CA, recipient province : nan, recipient city : Ontario, recipient postal code : nan, program name english : Engage Grants for universities, program name french : Subventions d'engagement partenarial pour les universités, program purpose english : The objective of this work is the development of advanced black chromium coatings by electroplating from_x000D_
trivalent chromium solutions. This project will be focused on active collaboration of Kuntz Electroplating Inc._x000D_
(KEI) and McMaster University. KEI is working on the development of new technology for electroplating of_x000D_
black Cr protective coatings for applications in automotive industry. KEI is interested in the solving of a_x000D_
problem of replacement of a Cr plating process from the hexavalent Cr solutions for a new plating process_x000D_
from the trivalent Cr solutions. The company has a problem of low electrodeposition yield of Cr coatings from_x000D_
Cr3+ solutions and significant cathodic gas evolution, which result in low adhesion, poor mechanical_x000D_
properties, low thermal shock resistance and poor corrosion resistance. KEI was not able to achieve black color_x000D_
of the coatings, which varied from gray to brown. The use of efficient complexing agents is of critical_x000D_
importance for electroplating from Cr3+ solutions. KEI is interested in new complexing agents and surface_x000D_
modification techniques, which are currently under development in the electrochemical laboratory of McMaster_x000D_
University. The unique features of new complexing agents are: good chelation of Cr3+ and other metal ions,_x000D_
which are used as plating additives, strong adsorption on Cr and Cr oxide additives, ability to facilitate ion_x000D_
reduction in solutions and improve charge transfer. Moreover, new chelating agents can impart black color to_x000D_
the coatings and hydrophobic properties. It is expected that the application of new chelating agents will result_x000D_
in the development of black Cr coatings with enhanced corrosion protection and mechanical properties,_x000D_
improved adhesion and thermal shock resistance. The development of black Cr coatings from Cr3+ solutions_x000D_
meets interests of Canadian automotive industry and offers many environmental benefits. The benefits of this_x000D_
project will include the generation of new technological solutions, technology transfer to KEI and HQP_x000D_
training. The resolution of the problem will result in job growth at KEI and increased revenue., program purpose french : The objective of this work is the development of advanced black chromium coatings by electroplating from_x000D_
