COMPARATIVE STUDY ON MICROSTRUCTURE AND PROPERTIES OF ELECTROLESS NI-P AND NI-CU-P COATINGS DEPOSITED ON PEEK

Comparative Study on Microstructure and Properties of Electroless Ni-P and Ni-Cu-P Coatings Deposited on PEEK

In order to better understand the advantages and disadvantages of Ni-P and Ni-Cu-P coatings, Ni-P and Ni-Cu-P coatings were deposited on surface of polyether ether ketone (PEEK) by electroless plating.Deposition Generators rates of electroless Ni-P coating and Ni-Cu-P coating under different processes were compared.Surface morphology, composition a

Frequency-Selective Limiters Using Triple-Mode Filters

This paper presents the first frequency-selective limiter (FSL) with both power-activation and user-prompted override that also features a reconfigurable threshold power and frequency tuning with closed-loop feedback.The FSL is based on a tunable absorptive bandstop-to-all-pass filter with integrated electronics.Three distinct modes are available:
