Evaluation of Diffusion Bonding (Welding) Process Temperatures of AISI 1010 Plain Carbon Steel with AISI 430 Ferritic and AISI 420 Martensitic Stainless Steels

Abstract In most applications, martensitic stainless steels are subjected to operating conditions in which good mechanical properties and wear resistance are required. CA6NM is a soft martensitic stainless steel that has high shear stress and toughness, good resistance to corrosion and cavitation, and better weldability than conventional martensitic stainless steels. These steels are susceptible to cavitation erosion which is the process of removing material due to the progressive action of erosive wear caused by the implosion of bubbles close to the surface of the mechanical element. Welding and thermal spraying are normally used to produce coatings when there is a need to increase the useful life of systems and parts, or in some cases for refurbishing. In this work 410NiMo martensitic stainless steel, in the form of wire and rod, were deposited by electric arc and flame thermal spraying processes respectively over a CA6NM martensitic stainless steel substrate. In order to improve the layer performance the sprayed coatings were remelted by the TIG welding process. The specimens were evaluated by accelerated cavitation according to ASTM G32-1 0 standard, Vickers microhardness, optical microscopy, X-ray diffraction, SEM and EDS. The tests showed coatings with low porosity and resistant to erosion by cavitation comparable with welded coatings. Making thermal spray with reflow by the TIG process an alternative in the application of this type of coating.

Carbon Filaments

Considerable effort has been directed toward an improved understanding of the production of the strong and stiff ∼ 1-20 μm diameter pyrolytic carbon fibers of the type reported by Koyama and, more recently, by Tibbetts. These macroscopic fibers are produced when pyrolytic carbon filaments (∼ 0.1 μm or less in diameter) are thickened by deposition of carbon during thermal decomposition of hydrocarbon gases. Each such precursor filament normally lengthens in association with an attached catalyst particle. The subject of filamentous carbon formation and much of the work on characterization of the catalyst particles have been reviewed thoroughly by Baker and Harris. However, identification of the catalyst particles remains a problem of continuing interest. The purpose of this work was to characterize the microstructure of the pyrolytic carbon filaments and the catalyst particles formed inside stainless steel and plain carbon steel tubes. For the present study, natural gas (∼; 97 % methane) was passed through type 304 stainless steel and SAE 1020 plain carbon steel tubes at 1240°K.

Abstract SAE 1025 is a plain carbon steel for general-purpose construction and engineering. It is used in the hot-worked, cold-worked, normalized or water-quenched-and-tempered condition. It also is carburized and used for case-hardened parts. Its many uses include bolts, forgings, axles, machinery components, cold-extruded parts, pressure vessels, case-hardened parts, chain and sprocket assemblies, spinning tools and permanent-mold castings. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness. It also includes information on corrosion resistance as well as forming, heat treating, machining, joining, and surface treatment. Filing Code: CS-114. Producer or source: Carbon steel mills.
