Protective layers for optical coatings
Surface Coatings International Part B: Coatings Transactions, 2006Protecting optical coatings represents an interesting area of applied science in which synthetic fluorine chemistry merges with surface science in support of thin film coating technology. This paper discusses the application of various fluorine-rich coatings materials as a means of protecting dielectric coatings against such factors as moisture ...

Evaluating non‐independent protection layers
Process Safety Progress, 2009AbstractThe overall performance of a system that shares inputs and outputs between the BPCS and SIS can be better than the performance of a BPCS system and SIS system with dedicated inputs and outputs. Layer of Protection Analysis (LOPA) assumes that independent protection layers (IPLs) are independent of the initiating event (IE) components and any ...

protective magnetite layer, layer thickness, x-ray diffraction
1999X-ray diffraction analysis has reduced a great service to metal industry by diagnosing cause of failures or cause of deficiencies of metals.For observation samples were take along deep drawn tube in the form of 10 x 10 mm plates. The x-ray diffraction patterns were collected at room temperature using the photographic technique, and CoK(alpha) radiation.

Optical Layer Protection and Restoration
1999This paper provides a brief overview of the network survivability options presented by the advent of Optical Networking. Included is an overview of survivability options for optical network architectures along with an analysis of critical challenges that lie in the path of widespread deployment of optical protection and restoration schemes.
