Corrosion of marine steel structures remains one of the major challenges in shipbuilding and offshore engineering, leading to significant maintenance costs, reduced operational reliability, and environmental concerns. The development of advanced protective coatings with improved durability and corrosion resistance is therefore an important research direction. Nanomodification of conventional...

H13 hot-work tool steel is widely preferred in hot forging, extrusion, and die-casting applications due to its high hardness, good thermal fatigue resistance, and dimensional stability at elevated temperatures; however, its wear resistance and surface durability under severe thermal and mechanical loading remain limited, necessitating protective surface coatings. In this study, Cr/CrN/CrAlN...

The F1 Halo component, mandated to protect drivers' heads, is manufactured from Grade 5 titanium (Ti-6Al-4V) per FIA Standard 8869-2018, yet strict weight limits make every kilogram critical to vehicle performance. This study investigates whether carbon fiber reinforced polymer (CFRP) composites can offer a lighter alternative to titanium without compromising FIA safety requirements. Six...

In recent years, we are increasingly seeing composite materials in the field of biomaterials, driven by esthetic, chemical, and mechanical demands associated with living tissue structures. From the perspective of materials engineering, desired new material forms can be created by combining the superior properties of the constituent materials that make up composite materials. The aim of this...

Machine-tool spindles are critical components whose performance directly affects machining accuracy, product quality, and service life. Contact and sliding between the spindle surface and its supporting components during operation can lead to wear, consequently reducing spindle service life and adversely affecting machining quality. AISI 7131 steel is commonly used for machine-tool spindle...

Surface degradation, wear debris generation, and metal ion release are major factors limiting the long-term performance of metallic biomedical implants. Nitrogen-based ceramic coatings, particularly titanium nitride (TiN), titanium carbonitride (TiCN), and titanium aluminum nitride (TiAlN), have attracted growing interest as surface modification strategies because they can enhance implant...

Titanium and titanium alloys are frequently preferred as biomaterials due to their unique properties. However, since the living body comprises a complex structure capable of constant change, doubts may always arise regarding the adequacy of material strength. Many new experimental methods are being developed to predict the time-dependent behavior of material strengths within the living body....
