Patent number: 9606076Abstract: The present invention is directed to a process for evaluating corrosion resistance of coated metals substrates, such as autobodies at accelerated rate. An anode and cathode coated with protective coating being tested are exposed to an electrolyte in a chamber of a corrosion resistance evaluator. These coatings are provided with predetermined and standardized defects, such as micro-holes to accelerate the corrosion of the underlying metal substrate in a predictable and repeatable manner. The coated cathode/anode pair is subject to a start-up period followed by series preset DC voltages modulated in a stepwise manner for preset durations that are interspaced with recovery periods. The impedance data collected are then used to arrive at the corrosion performance resistance of the coating applied over the cathode/anode pair. The foregoing evaluator substantially reduces the time required to test corrosion from several days (40 plus days) to few days (about two days).Type: GrantFiled: December 21, 2011Date of Patent: March 28, 2017Assignee: AXALTA COATING SYSTEMS IP CO., LLCInventors: Shi Hua Zhang, Lorenzo Fred Pelosi, Robert C.

Patent number: 9476820Abstract: A corrosion resistance evaluator is provided for evaluating corrosion resistance of coated metals substrates, such as autobodies, at an accelerated rate. The evaluator includes a chamber for retaining an electrolyte that is exposed to an anode and cathode coated with protective coating being tested. These anode and cathode coatings are provided with predetermined and standardized defects, such as micro-holes, to accelerate the corrosion of the underlying metal substrate in a predictable and repeatable manner. The evaluator further comprises an anode holder and a cathode holder for testing the corrosion resistance of the anode and cathode coatings. The evaluator substantially reduces the time required to test corrosion from several days (40 plus days) to few days (about two days).Type: GrantFiled: September 23, 2014Date of Patent: October 25, 2016Assignee: AXALTA COATING SYSTEMS IP CO., LLCInventors: Shi Hua Zhang, Lorenzo Fred Pelosi, Robert C.

An anode and cathode coated with protective coating being tested are exposed to an electrolyte in a chamber of a corrosion resistance evaluator. These coatings are provided with predetermined and standardized defects, such as micro-holes to accelerate the corrosion of the underlying metal substrate in a predictable and repeatable manner. The coated cathode/anode pair is subject to a start-up period followed by series preset DC voltages modulated in triangular, truncated triangular or trapezoidal manner for preset durations that are interspaced with recovery periods. The impedance data collected are then used to arrive at the corrosion performance resistance of the coating applied over the cathode/anode pair. The foregoing evaluator substantially reduces the time required to test corrosion from several days (40 plus days) to few days (about two days).Type: GrantFiled: December 21, 2011Date of Patent: December 15, 2015Assignee: AXALTA COATING SYSTEMS IP CO., LLCInventors: Shi Hua Zhang, Lorenzo Fred Pelosi, Robert C Nahas
