摘　　要：客运专线道岔采用的滑床垫板中,滑床台板直接承载来自轮轨的荷载,应具有良好的综合性能。近年来,科研单位和制造厂家不断研制更适用、性价比更高的滑床台板。总结滑床台板技术研究中的相关工作,对比激光涂覆硬化滑床台板、铌钒钛不锈钢滑床台板、复合滑床台板等滑床台板的技术特点,以推动其研发和制造工作。For the sliding chair used in PDL turnouts, it directly stands the load from wheel track, thus shall besound in overall performance. In recent years,research institutes and manufacturers have been developing more ap-plicable sliding chairs with a better performance-to-price ratio constantly. The article summarizes the work related tothe technical study on sliding chairs. It compares the technical features in such new sliding chairs as the laser-coated hardened sliding chairs,the titanium, vanadium niobium containing stainless steel sliding chairs and the com-pound sliding chairs,etc.,which help to further promote its development and improve its manufacturing.
