Abstract: The increasing demand for higher precision and efficiency in machining processes has led to the exploration of self-lubricating tool coatings as a solution to reduce tool wear and maintenance in high-load machining processes. Self-lubricating coatings are designed to enhance the performance of cutting tools by providing continuous lubrication during machining, which minimizes friction and wear, especially in high-temperature environments. This research investigates the development and performance of advanced self-lubricating coatings, focusing on their impact on tool life, surface quality, and overall process efficiency in high-load machining applications. Various materials, including composite coatings, nanostructured films, and ceramic-based coatings, are evaluated for their lubrication properties and ability to withstand the extreme conditions of high-load machining. The coatings are characterized using scanning electron microscopy (SEM), X-ray diffraction (XRD), and tribological testing to assess their wear resistance, adhesion strength, and self-lubricating efficiency. The findings indicate that self-lubricating coatings significantly improve tool performance by reducing friction and wear, thus extending tool life and decreasing the need for frequent maintenance. Furthermore, the coated tools exhibit better surface finish on machined parts, contributing to the overall efficiency of machining processes. The research also explores the challenges in developing durable and effective self-lubricating coatings, such as material selection, coating application methods, and the integration of lubrication mechanisms at the micro and nano scales. This research aims to contribute to the development of advanced tool coatings that can meet the growing demands of modern machining industries while reducing maintenance costs and improving operational sustainability.
