Iron Plating

Zn–Ni plating is indispensable in various industries because of its high corrosion resistance. However, Ni has been reported to trigger allergies; thus, an alternative Ni-free plating is desired. Zn–Fe plating is considered to be a promising candidate, albeit its corrosion resistance still needs to be improved. The corrosion resistance of Zn–Fe plating is expected to increase by the addition of Mo as the third alloying element as it is more noble than Zn and Fe. In this study, Zn–Fe–Mo plating with a corrosion resistance nearly equivalent to that of the Zn–Ni plating was fabricated. Zn–Fe–Mo plating was electrically deposited from continuously agitated plating baths prepared by mixing ZnSO4, FeSO4, Na2MoO4, Na3C6H5O7, and Na2SO4 using Fe or Ni plates as the substrate. The surface morphology, composition, crystal phase, and electronic state of Mo of the platings were investigated by SEM-EDS, XRD, and XPS. The anti-corrosion performance was evaluated by Tafel extrapolation method. Formation of plating comprising a Mo containing alloy phase was found to be crucial for improving corrosion resistance. The Zn–Fe–Mo plating demonstrates promise for replacing anti-corrosion Zn–Ni platings.

[Objective] The purpose of this study was to evaluate the variation of surface morphology of titanium alloy after sand blasting with different particle sizes of Al2O3sand and acid etching, and its corrosion resistance property. [Methods] The surfaces of titanium alloy were first treated with the different sands and then acid etched with mixture of 18% HCl and 48% H2SO4. The morphology of samples was investigated by scanning electron microscopy (SEM). The potentiodynamic polarization curves of the various surfaces were obtained by electrochemical workstation (CHI 660E) in simulated body fluid (SBF). [Results and conclusions] It is observed that pore sizes on surface increases with the increase of sand grain diameter while there is no obvious change after acid etching. After sand blasting and acid etching, the corrosion resistance of titanium alloy was improved. However, as the pore size of the surface increases, the corrosion resistance gradually degrades and this becomes even more obvious after acid etching. The investigation of the corrosion rate indicates there is an increasing trend with the emergence of small pores.

Traumas and diseases of the musculoskeletal system are the second among the causes of temporary disability of the population, and the third among the causes of disability and mortality. An effective method of treatment is endoprosthetics. ; Every year across the globe 500-1000 patients per 1 million of population require prosthetics. The development of endoprostheses is progressing in various spheres: design of the implant parts, methods of fixation, use of various materials, different types of surface finish of implants. Endoprostheses that are currently produced and used in traumatology and orthopaedics are unified, i.e. ; standardized - all of them have different size, but their shape is the same. This imposes serious limitations on the use of implantation in difficult clinical cases. The way out can be the use of personified implants, designed and manufactured with the use of modern rapid prototyping technologies. In this case, the use of titanium will fully implement the most important advantages of this direction: the best biocompatibility, high corrosion resistance, low modulus of elasticity, high specific strength and endurance.

High requirements in biomedical application are associated with biocompatibility and high corrosion resistance of metal biomaterials, which are used equally in joint and bon substitution and the healing and renewal of bone weaknesses. In this paper the surface morphology and electrochemical properties of samples manufactured by Selective Laser Melting SLM method using pure titanium Grade II powder material are explored. The tested samples were produced divided into four group, depended on the values of basic process parameters – laser power P, scanning speed SP and point distance PD. The value of energy density E delivered to the sintered material was constants and was an approximately E = 75 ± 2 J/mm3. In the paper, the pitting corrosion test by recording anodic polarization curves and electrochemical spectroscopy test were carried out. Additionally the microscopic observation and microchemical analysis by SEM/EDS analysis and material density measurements were performed too. Based on the obtained results it can be concluded that the laser power P and scanning speed SP have a significant affect on the obtained full density defect free material with high corrosion resistance.
