Sheet Resistance Measurement of Thin Films, Four-Probe Method | Ossila

Unlike others on the market, Ossila''s Four-Point Probe System is capable of giving you accurate sheet resistance measurements without causing damage to thin films, all thanks to its rounded, spring-loaded probes. Sheet resistance (or surface resistivity) is an important property of many materials, quantifying the ability for charge to travel along uniform thin films.

Journal Bearings - an overview | ScienceDirect Topics

P.R.N. Childs, in Mechanical Design (Third Edition), 20212.1 Introduction The purpose of a bearing is to support a load, typically applied to a shaft, whilst allowing relative motion between two elements of a machine. The two general classes of bearings are journal bearings, also known as sliding or plain surface bearings, and rolling element bearings, sometimes also …

Lubriion Regimes Explained

Oil films are typically in the order of 2 to 100 microns (0.00008 to 0.004 inches) thick. They can be larger (300 microns or 0.012 inches) in very large diameter journal bearings. Lada values (oil film thickness to surface roughness ratio) are usually greater than 2.

Chrome Coating Surface Adhesion & Masking | Electro-Coating

Hard Chrome Surfaces: Adhesion, Masking, Grinding, Finishing. Although it is often said that the chromium layer will reproduce faithfully every defect in the base material, in actuality as the chrome deposit thickens it will level imperfections. For smooth as-is chrome plating, the basis material should be at least as smooth as the expected chrome.
