Friction surfacing of stainless steel over low carbon steel and charecterization of deposit

Abstract

Surface engineering deals with the surface of a solid matter and it is the sub-discipline of materials science. The surface phase of a solid when interacts with the surrounding environment, degrades over time, and may result in loss of material from its surface. Environmental degrada-tion of the surface phase over time can be caused by corrosion, wear, fatigue loads, creep, cutting forces, shear, tension, or when exposed to higher temperature. Major types of wear include friction, erosion, abrasion and corrosion. Wear can be minimized by modifying the surface properties of solids by surface finishing or by use of lubricants. The corrosion will affect not only the metals, but also the non-metals like plastics, rubber, ceramics, etc. Corrosion is a slow process and except noble metals such as gold and platinum, there is no material which can withstand corrosive attack in all environments. Corrosion affects both the performance and the life of the devices which are used in various fields. Surface engineering involves altering the properties of the solid surfaces which could be different from those of the core material to reduce the degradation over a time. These are also used to impart a wide range of functional properties, including physical, chemical, electrical, electronic, magnetic, mechanical, wear-resistant and corrosion-resistant properties at the required substrate surfaces. Almost all types ofmaterials, including metals, ceramics, polymers, and composites can be coated on materials, similar or dissimilar. Surface engineering techniques are being used in the automotive, aerospace, missile, power, electronic, biomedical, textile, petroleum, petrochemical, chemical, steel, power, cement, machine tools and in construction industries. Low carbon steel is easily available and machinable at low cost, so it is generally preferred in industry and other fields for making machine elements and components.
