Research Progress on Laser Cladding of Carbide Reinforced Titanium Based Cemented Carbide Coatings
摘要
Abstract
Titanium alloys have been widely used in aerospace,medical equipment and other fields due to their good density,corrosion resistance and biological activity.However,their service life under friction condition is seriously restricted due to insufficient hardness,poor wear resistance,high temperature oxidation and poor biocompatibility.In order to solve these problems,a series of researches have been carried out in ceramic materials with high hardness,high wear resistance,high temperature oxidation resistance and laser cladding layers.In this paper,the effects of laser energy,scanning speed,spot diameter,specific energy and powder content on the wear resistance of the coatings are discussed.Through systematic experiments and data analysis,the ways by which these key factors interact to improve the durability of coatings are revealed.The research results provide valuable information for optimizing the laser processing technology and help to design more wear-resistant coating products.Then,the application of laser cladding technology in the preparation of SiC-strengthened titanium based solid solution carbon coatings is analyzed.In this paper,the excellent abrasive resistance is analyzed in detail,including abrasive wear and surface fatigue crack resistance tests.These experiments enable better understand how the laser cladding process affects the performance of coatings and the potential value of this technology in improving the durability of industrial equipment.At the same time,the corrosion resistance of the coatings is studied in depth,especially in wet environments.In addition,the focus is also put on the oxidation resistance of the coatings at high temperature and the mechanical strength and toughness under high stress.The evaluation of these properties provides an important basis for the practical application of the new coating materials,and the corrosion resistance of the coatings is discussed.The corrosion resistance of the coatings to various chemicals is evaluated in detail,especially in wet environments.In addition,special attention is paid to the oxidation resistance of the coatings at high temperature,as well as their mechanical strength and toughness under high stress.The comprehensive evaluation of these key characteristics provides a solid theoretical basis for the commercial application of this new coating material.Finally,a novel coating system based on in-situ synthesis and gradient composite design strategy is investigated.These advanced methods can not only improve the performance of coatings,but also show excellent application potential in many key industrial fields.In the field of aerospace in particular,these coatings can significantly improve the durability and safety of aircraft structures;In the field of biomedicine,they can provide a higher level of biocompatibility and antimicrobial resistance for medical devices;In marine engineering,they can be used to protect deep-sea equipment from seawater corrosion;And in the metallurgical industry,they can enhance the corrosion resistance and mechanical properties of metallic materials.Through the elaboration of these applications,it is expected to provide an innovative and efficient solution to the growing technical challenges and market demands of the relevant industries.In this review,this work not only reviews and analyzes the progress of the research,but also looks forward to its development trend and prospects,so as to provide guidance and inspiration for future research.关键词
