According to Ispat Guru: Role of Lubrication during the Process of Metal Working For understanding the role of lubrication during the processes of metal working, it is important to know the tribology of the lubrication. Tribology consists of boundary friction, which is associated with almost all operations of the metal working. It is caused by the relative movement of two adjacent surfaces under pressure. During the metal working processes, the relative movement between rolls and work piece is improved by the surface speed differential of the rolls Friction Friction plays an important role during metal working process. It is defined ...

According to Chemistry Page: Surface chemistry is a discipline about the physical and chemical properties of solid and liquid surfaces or phase interfaces. Its contents include, for example, the adsorption and segregation of solutes on the solution surface, the infiltration of liquids on solid surfaces, and the adsorption of gases on solid surfaces, which are closely related to the actual production. Early surface chemistry studies were mainly phenomenological descriptions of related surface or interface properties. Since the 1960s, due to the need for further development of some important technical fields related to solid surfaces, such as solid materials, devices, heterogeneous catalysis, ...

According to Powder Coating Online: Rejects from coating lines can come from a substrate defect, a surface contaminant or a coating material defect. Process controls should be implemented upstream of the coating line to prevent a defective substrate from entering the line. If a substrate is defective and has entered the coating line, it is important to recognize the source of the blemish and not waste time trying to fix the coating process to correct a pre-existing substrate condition. Dirt on the surface of a coated part is a major concern for all coaters. Dirt may come from the air around ...

According to Products Finishing: Anyone responsible for the implementation of a cleaning step within a manufacturing operation should understand the relationship between the cleaning process and the cleaning equipment. Though the two are different entities, they form a necessary symbiotic relationship. If either component fails to perform, the entire operation fails. On too many occasions, an engineer might assume that a standard cleaning system configuration will get the job done, only to be disappointed that it doesn’t meet expectations. The process cleans the parts and the equipment delivers that process; the two elements cannot perform independently. Cleaning is simply filling ...

According to Production Machining: In an industry in which production time, volume and quality are critical, it’s increasingly important to ensure that metal parts obtain desired results and meet established specifications. Since metal parts cleaning is fast becoming the industry standard, facility managers must become well-versed in the extensive cleaning processes and chemistries available that will provide the performance level required. It is essential for these managers to learn the differences between aqueous and solvent cleaning solutions, and the advantages and disadvantages of using each approach. Metal parts need to be cleaned after they are manufactured to remove oil, chips ...

Reinforcing bars? Consider a water-based corrosion inhibitor. According to Materials Performance: "Deformed steel reinforcement (rebar) is a widely used steel product, especially in the construction industry, used in buildings, bridges, roads, etc.1 However, in the transportation and the storage process, uncoated rebar is often corroded by the corrosive environments. The corrosion product of the rebar surface reduces gripping force to concrete and affects the quality of the whole construction. "The rust on the rebar surface is one of the major factors that influences the durability of the building.2-3 As an anticorrosive measure for rebar, the use of oil has obvious ...
