Wear resistant solid lubricant coating made from PTFE and epoxy
A composite coating of polytetrafluoroethylene and epoxy shows 100 · improvements in wear resistance as compared to either of its constituents alone and reduced friction coefficient under testing on a pin-on-disk tribometer. This coating is made by impregnating an expanded PTFE film with epoxy, which provides three unique functions: (1) the epoxy compartmentalizes the PTFE nodes, which is belie...
متن کاملFormation of a hybrid coating by the use of plasma nitriding and hard chromium electroplating on the surface of H11 hot work tool steel
Abstract: Formation of a hybrid coating by the use of plasma nitriding and hard chromium electroplating on the surface of H11 hot work tool steel was investigated. Firstly, specimens were plasma nitrided at a temperature of 550 °C for 5 hours in an atmosphere of 25 vol. % H2: 75 vol. % N2. Secondly, electroplating was carried out in a solution containing 250 g/L chromic acid and 2.5 g/L sulp...
متن کاملIon Plating Can Improve Coating Adhesion
1. Easy to plate: steel, copper and brass. These can be coat* with adherent deposits that will riot fail at the deposit-substrate interface. 2. Special treatment: stainless steels, aluminum, beryllium, magnesium and plastics. These can also be coated with adherent deposits that will not fail at the deposit-substrate interface. 3. Very difsicult: titanium, molybdenum, tungsten, niobium, tantalum...
متن کاملINVESTIGATION OF CHROMIUM AND VANADIUM CARBIDE COATING FORMATION ON SKD11 AND T10 BY THERMO-REACTIVE DIFFUSION (TRD) METHOD
Carbide coatings, due to their excellent anti-wear properties, are used to extend the life of molds exposed to abrasion forces. Various processes have been applied to produce carbide coatings. Thermo-reaction diffusion (TRD) using a molten salt bath could be considered as an economical method compared to other coating processes. In this study carbide-composite coatings using molten salt baths c...
متن کاملPlating, Finishing, and Coating: State-of-the-Art Assessment
This report focuses on the surface finishing of metals or metal finishing as it is usually called. Because of the wide range of techniques used and the similarity between some of the techniques, a classification system was devised to organize the presentation of the material. Metal finishing activities have been divided into (1) pretreatments, which include cleaning and surface preparation, (2 ...
