Abstract:

The purpose of this study was to investigate the influence of synthesis parameters and surface finish on the corrosion of DMLS-printed M300 steel components and to evaluate their applicability in corrosive environments. In order to assess the influence of the corrosive environment, potentiodynamic and long-term corrosion tests were carried out in this study, together with microscopic and EDS studies on 3D-printed M300 steel samples synthetized using the DMLS method with different laser powers. The results show that DMLS-produced M300 steel is vulnerable to corrosion in corrosive environments.

Corrosion is a chemical reaction between metal and chemical substances in free air influenced by typographical conditions, climate, and humidity levels around the metal object. If left unchecked, it can cause damage to the metal infrastructure, material losses, and harm in terms of safety and security. Therefore, a way to inhibit corrosion is needed by creating an environmentally friendly inhibitor from natural materials. One of them is by utilizing Sambiloti leaf as a natural inhibitor. Sambiloto leaves contain tannins which can inhibit corrosion well. This study aimed to determine the effici

The interaction of wear and corrosion is an important factor of the combined action of mechanical and corrosive damage. Many authors have studied the synergistic effect between wear and corrosion under different contact conditions. In the present paper is proposed a simplified method to predict wear evolution of contact surfaces in corrosive environment based on the wear loss evolution in dry conditions and on the coefficient of friction in corrosive environment. The proposed method is adequate to properly predict the wear loss evolution.

The fatigue crack initiation life and growth rate are affected by experimental conditions. A corrosive environment can be created in a laboratory by means of dropping salt water onto the specimen surface, spraying chloride mist into the experimental chamber, etc. In the case of smooth specimens of some metals, fatigue life is shortened and the fatigue limit disappears under such corrosive experimental conditions. In this study, the effects of intermittent spraying of 3% NaCl solution-mist on corrosion fatigue behavior were investigated. The material used was 0.37% carbon steel. This is called

In this work, the corrosive effect of RuO2 coatings that were produced by the thermal decomposition of RuCl3 is reported.

Abstract:

The corrosion of metal substrates is closely associated with the permeability of the corrosive medium in which they are immersed. To enhance the protection of metal materials and improve anti-corrosion performance from an epoxy resin perspective, the diffusion path complexity can be increased and porosity reduced within the epoxy resin coating to effectively block the invasion of corrosive media. Simultaneously, reducing the affinity between the corrosive media and the epoxy resin coating makes it difficult for corrosive substances to adhere.

The durability problem in high-strength steel wire used for bridge cable is becoming more and more severe due to chlorine salt erosion, with the primary corrosion morphology of steel wire surfaces being pit corrosion. To simplify the pitting formation process, a machine-cut notch was used to represent a corrosion pit caused by electrochemical non-uniformity, and then the fatigue performance and corrosion fatigue performance of steel wire with initial defects were studied experimentally. A new type of test device was designed to carry out synchronous pulsating fatigue loading on multiple wires.

Abstract:

According to the stable opinion, hydrogen absorbed by magnesium alloys during corrosion can cause their stress corrosion cracking. One of the characteristic markers indicating the involvement of diffusible hydrogen into the fracture mechanism of metals is the negative strain rate dependence of the embrittlement degree. Recent studies show that the loss of ductility of the ZK60 alloy specimens subjected to a short-term (1.5 h) pre-exposure in a corrosive medium actually decreases with the increasing strain rate.

Temperature is the important factor for the reaction of corrosive sulfur with copper.
