چکیده
The paper presents the results of comparison quality indices brake shoes for railroad rolling stock made synthetic cast iron smelted in induction furnaces and composite material which is a vulcanized mixture rubber different fillers. Disclosed are disadvantages pads. Defects working surface railway wheels caused by application pads rubber-asbestos or shown. Parameters C, Si, Mn, P, S content carbon equivalent distribution used production «M» type according to GOST 30249-97 analysed. It established that hardness fracture strength do not correlate with chemical elements its equivalent. ranges distributions specified purpose much narrower than allowable limits these 30249–97. Suggestions improving standards given.

Characterization of Friction Material Formulations for Brake Pads
techniques such as SEM, TGA, XRD, friction and wear tests are used to characterize the formulations as well as the commercial material. Out of the 30 formulations made, two formulations viz., S1 and S2 closer to commercial material are presented in this work. Formulation S2 exhibits better thermal stability and better wear resistance. With the help of SEM analysis, physical properties and XRD s...
متن کاملThe Mechanism of Changes in the Surface Layer of Grey Cast Iron Automotive Brake Disc
The aim of the study was to create a model, describing the run of tribological processes in the surface layer of grey cast iron automotive brake discs. Grey cast iron discs mating with non-asbestos organic brake pads were chosen for the investigations, as the most widely used materials in car brakes. Samples for surface analysis were prepared from disc operating in stand and road conditions. St...
متن کاملResin-based Copper-free Brake Pads: A Right Selection of Potassium Titanate and Ceramic Fiber
The present study aimed to assess the effect of replacing copper as a multi-functional ingredient in the brake pad material with potassium titanate platelet (PTP) and a particular type of ceramic fiber (CF) copper-free composite. Chase dynamometer tests were conducted to compare a brake padchr('39')s tribological behavior when PTP and CF are added to the composition with that of the copper-bear...
متن کاملCast Iron Metallurgy
Cast iron (CI) is one of the oldest materials in commercial use. It has excellent compressive strength and is commonly used for structures that require this property, as well as for water and sewer lines. This article explains CI metallurgy and why the understanding of this metallurgy is key to understanding other ferrous materials and alloys. The composition of cast iron (CI) varies significan...
متن کاملComparative Analysis of Spectral and Spatial Features for Classification of Graphite Grains in Cast Iron
The morphology and the distribution of graphite grains are the decisive factors in judging the properties of the material cast iron. There are six classes of graphite grain morphology defined by ISO-945 through reference drawings for cast iron graphite grain classification. These reference drawings are universally accepted for classification of graphite grains. Many shape representations and re...
