Abstract

The UNS 31254 (SS 254) stainless steel has a wide range of medical applications. However, its low biomedical and corrosion resistance limits its use in the medical field. To address this challenge, the Low-Velocity Oxy-Fuel (LVOF) technique was used to apply coatings of hydroxyapatite (HA), (HA+10 wt% micrometric - Al₂O₃), and (HA+10 wt% nanometric-Al₂O₃) to the SS 254 substrate. The reinforced HA coatings were annealed at 400 °C and 800 °C for 2 h. Field emission scanning electron microscopy (FE-SEM), X-ray diffraction (XRD), electrochemical corrosion tests, and in-vitro bioactivity investigations were used to evaluate the performance of coatings. The XRD analysis revealed the phases present and assessed the crystallinity of the coatings. Additionally, the sintering effect produced by annealing resulted in a notable decrease in porosity. The annealing of HALN at 800 °C for 2 h has minimized the undesired phases (α-TCP and β-TCP) developed during coating thereby leading to improved crystallinity and densification of the coatings. The enhancement in annealing temperature increased the coating's corrosion resistance and reduced the bioactivity of coatings.

SS 254外科级生物植入材料上ha基LVOF喷涂和退火涂层的生物相容性和腐蚀性能

UNS 31254 （SS 254）不锈钢具有广泛的医疗应用。然而，其低生物医学和耐腐蚀性限制了其在医疗领域的应用。为了解决这一挑战，使用低速氧燃料（LVOF）技术将羟基磷灰石（HA），（HA+ 10wt %微米-Al₂O₃）和（HA+ 10wt %纳米-Al₂O3）涂层涂在SS 254衬底上。将增强羟基磷灰石涂层分别在400°C和800°C退火2 h。采用场发射扫描电镜（FE-SEM）、x射线衍射（XRD）、电化学腐蚀测试和体外生物活性研究来评价涂层的性能。XRD分析显示了涂层的物相，并对涂层的结晶度进行了评价。此外，退火产生的烧结效应使孔隙率显著降低。HALN在800℃下退火2 h，最大限度地减少了涂层过程中产生的不良相（α-TCP和β-TCP），从而提高了涂层的结晶度和致密性。退火温度的提高提高了涂层的耐蚀性，降低了涂层的生物活性。

期刊介绍： Ceramics International covers the science of advanced ceramic materials. The journal encourages contributions that demonstrate how an understanding of the basic chemical and physical phenomena may direct materials design and stimulate ideas for new or improved processing techniques, in order to obtain materials with desired structural features and properties. Ceramics International covers oxide and non-oxide ceramics, functional glasses, glass ceramics, amorphous inorganic non-metallic materials (and their combinations with metal and organic materials), in the form of particulates, dense or porous bodies, thin/thick films and laminated, graded and composite structures. Process related topics such as ceramic-ceramic joints or joining ceramics with dissimilar materials, as well as surface finishing and conditioning are also covered. Besides traditional processing techniques, manufacturing routes of interest include innovative procedures benefiting from externally applied stresses, electromagnetic fields and energetic beams, as well as top-down and self-assembly nanotechnology approaches. In addition, the journal welcomes submissions on bio-inspired and bio-enabled materials designs, experimentally validated multi scale modelling and simulation for materials design, and the use of the most advanced chemical and physical characterization techniques of structure, properties and behaviour. Technologically relevant low-dimensional systems are a particular focus of Ceramics International. These include 0, 1 and 2-D nanomaterials (also covering CNTs, graphene and related materials, and diamond-like carbons), their nanocomposites, as well as nano-hybrids and hierarchical multifunctional nanostructures that might integrate molecular, biological and electronic components.
