本发明属于热喷涂领域，涉及一种基于道宽与道距约束的切向功能梯度涂层过渡区设计及性能预测方法，设计合理的过渡区结构，包括以下步骤：步骤1：确定涂层生长率分布函数和道宽；步骤2：基于道宽与道距约束，确定过渡区多道距搭接结构，具体包括确定道距、过渡区宽度、搭接层数；步骤3：利用面积加权法计算过渡区各位置处涂层的当量复合比，预测过渡区各位置处涂层的抗冲蚀性能。采用本发明制备的切向功能梯度涂层过渡区，涂层各过渡区遵循一致的过渡规律，过渡区抗冲蚀性能过渡平稳、可预测。 A design method and performance prediction method for transition regions of a tangential functionally gradient coating on the basis of the constraints of track width and track distance, which belong to the field of thermal spraying and are used for designing a reasonable transition region structure. Said methods comprise the following steps: step 1, determining a coating growth rate distribution function and a track width; step 2, on the basis of the constraints of track width and track distance, determining a multi-track distance lap-joint structure of a transition region, specifically including determining a track distance, a transition region width and the number of lap-joint layers; and step 3, calculating an equivalent composite ratio of a coating at each position of the transi
