In accordance with one embodiment, a system is presented. The system includes a casing (36), a combustor (12) disposed within the casing (36), and a sensing device (38) located on the casing (36) andconfigured to sense a plurality of acoustic emission waves and generate an electrical signal based on the sensed plurality of acoustic emission waves. The system further includes a processing subsystem operationally coupled to the sensing device (38) and configured to determine one or more features based on the electrical signal, and determine a presence or an absence of fretting wear in the combustor (12) based at least on the one or more features. 根据个实施例，提供种系统。所述系统包括外壳(36)、设置在所述外壳内的燃烧器(12)以及感测装置(38)，所述感测装置(38)位于所述外壳(36)上并且配置成感测多个声发射波，并且基于感测到的多个声发射波生成电信号。所述系统进步包括处理子系统，所述处理子系统操作性地连接到所述感测装置(38)并且配置成基于所述电信号确定个或多个特征，并且至少基于所述个或多个特征确定所述燃烧器(12)中微振磨损的存在或不存在。
