Abstract

Purpose

The purpose of this paper is to study the effect of surface salt spray duration on the fretting wear and electrochemical corrosion behaviors of Inconel 690 alloy.

Design/methodology/approach

A high-temperature steam generator was applied to salt spray test samples, a fretting wear rig was used to realize the damage behavior tests, an electrochemical workstation was applied to analysis the changes of each sample’s corrosion dynamic response before and after fretting wear.

Findings

The thickness of the oxide film that formed on sample surface was increased with the salt spray duration, and somewhat it could act as lubrication during the fretting wear process; however, the corrosive chloride would accelerate the fretting mechanical damage behavior.

Originality/value

In a salt steam spray condition, the fretting tribo-corrosion behaviors of Inconel 690 alloy surface was studied.

盐雾持续时间对 Inconel 690 合金管材摩擦腐蚀行为的影响

本文旨在研究表面盐雾持续时间对 Inconel 690 合金的烧蚀磨损和电化学腐蚀行为的影响。设计/方法/途径对盐雾试验样品采用高温蒸汽发生器，使用烧蚀磨损台架实现损伤行为试验，应用电化学工作站分析每个样品在烧蚀磨损前后的腐蚀动态响应变化。研究结果样品表面形成的氧化膜厚度随盐雾持续时间的延长而增加，在一定程度上可以在烧蚀磨损过程中起到润滑作用；但腐蚀性氯化物会加速烧蚀的机械损伤行为。

期刊介绍： Anti-Corrosion Methods and Materials publishes a broad coverage of the materials and techniques employed in corrosion prevention. Coverage is essentially of a practical nature and designed to be of material benefit to those working in the field. Proven applications are covered together with company news and new product information. Anti-Corrosion Methods and Materials now also includes research articles that reflect the most interesting and strategically important research and development activities from around the world. Every year, industry pays a massive and rising cost for its corrosion problems. Research and development into new materials, processes and initiatives to combat this loss is increasing, and new findings are constantly coming to light which can help to beat corrosion problems throughout industry. This journal uniquely focuses on these exciting developments to make essential reading for anyone aiming to regain profits lost through corrosion difficulties. • New methods, materials and software • New developments in research and industry • Stainless steels • Protection of structural steelwork • Industry update, conference news, dates and events • Environmental issues • Health & safety, including EC regulations • Corrosion monitoring and plant health assessment • The latest equipment and processes • Corrosion cost and corrosion risk management.
