ABSTRACT Many metallic components are frequently subjected to coupled environments of friction and vibration, stemming from interfacial contact and relative motion between mating parts or external stimuli. Consequently, it is imperative for these components to exhibit a synergy of high wear resistance and superior damping properties.

State of the Art of Laser Hardening and Cladding
In this paper an overview is given about laser surface modification processes, which are developed especially with the aim of hardness improvement for an enhanced fatigue and wear behaviour. The processes can be divided into such with and without filler material and in solid-state and melting processes.

Inverse‐Designed Silicon Nitride Bimodal Mode Converter for Interferometric Sensors
Inverse‐designed bimodal mode converters are demonstrated on two silicon nitride platforms. The devices convert the fundamental mode into near‐balanced pairs of the fundamental and higher‐order modes up to the third order. They are compact and fabrication‐tolerant. Characterization of a bimodal interferometer incorporating these converters demonstrates
