Introduction

Due to factors affecting the performance of many anti-rust oil rust, a single multi-electrode electrochemical test rapid test does not represent an absolute anti-rust oil Rust resistance, so the test results are not obtained in this standard as the test sample directly guide the use of anti-rust performance in all environments. in spite of Thus, the method specified in this standard is still available as a method of comparing the merits of the test sample rust resistance. Anti-rust oil rust performance test Multi-electrode electrochemical

1 Scope

This standard specifies the evaluation of anti-rust oil rust resistance test multi-electrode electrochemical test methods, equipment and procedures. This standard applies to the iron-based material comparative test of anti-rust oil rust resistance.

3 Terms and Definitions

GB/T 11372 and established the following terms and definitions apply to this standard. 3.1 Rust performance rustpreventingability Rust oil effective protection under the metal film or the ability to prevent corrosion of the metal. 3.2 Multi-electrode electrochemical electrochemicalmeasurementwithwirebeamelectrode By measuring a plurality of electrodes in oil or oil-coated electrode electrochemical parameters in corrosive media, and the use of statistical parameters to evaluate the anti-rust oil Rust resistance method. The former is called a multi-electrode electrochemical direct measurement method, which is called a multi-electrode electrochemical drain method. Principle 4 Rust coating film at room temperature corrosion of metals is a electrochemical process. The resistance encountered during mainly from polarization resistance, which Or second film is corrosive resistance. The resistance encountered during the greater the corrosion rate of the metal is smaller. In the film and the polarization resistance is greater than Corrosive media resistance condition, the greater the measured resistance, anti-rust anti-rust oil, the better the performance. Electrochemical unevenness anti-rust oil, each Electrode resistance generally different. Low resistance region is the weak link in protective anti-rust oil, the first cause metal corrosion under the membrane, the direct control of the film Rust performance advantages and disadvantages. Multi-electrode electrochemical method to evaluate the performance of rust rust film by statistical distribution of low-resistance electrode resistance area.
