The invention discloses a test method used for corrosive wear. The method comprises the following steps: calculating the metal corrosion current ik through combining the local cathodic reaction polarization curve of an inert electrode with the self-corrosion potential Ecorr of a corrosion electrode; calculating the metal corrosion current density icorr; and converting the corrosion weight loss rate Wcorr according to the Faraday's law. The test method for simulating the corrosive wear service condition is provided against the dynamic corrosion and wear service test under wear and corrosion conditions when the surface brittle delamination caused by a cutting furrow and impact corrosion wear environment is the main cause for the failure of an anti-wear part containing a corrosion medium. The method solves and determines the measurement of the total corrosive wear weight loss of a metal material in the corrosion medium, can be used for measuring the electrochemical corrosive wear in dynamic corrosive war, and effectively instructs the quantitative researches of the corrosion in the wearing process.
