Alloy-4J29 ha e na feela katoloso ea mocheso e tšoanang le khalase, empa sekhahla sa eona sa ho atolosa mocheso se sa tloaelehang se ka etsoa hangata hore se lumellane le khalase, kahoo se lumella hore motsoako o mamelle mocheso o pharaletseng. Ka lik'hemik'hale, e tlamahane le khalase ka lera la oxide e bohareng ea nickel oxide le cobalt oxide; karolo ea tšepe ea oxide e tlase ka lebaka la ho fokotseha ha eona ka cobalt. Matla a tlamahano a itšetlehile haholo ka botenya ba oxide layer le sebopeho. Ho ba teng ha cobalt ho etsa hore oxide layer e be bonolo ho qhibiliha le ho qhibiliha ka khalase e qhibilihisitsoeng.
