Abstract:
An anti-galling method for treating materials, which provides for subjecting at least one of the at least two components mutually coupled with at least one degree of freedom, made of metallic material, to a first preliminary step of thermal treatments to increase surface hardness and to a second preliminary step of surface grinding, which consists in - performing a first step of washing at least one portion of the surface of the at least one component subjected previously to the preliminary steps; - performing a second step of shot peening the at least one portion of the surface of the at least one component previously subjected to washing; - performing a third step of applying a layer of molybdenum disulfide to the at least one portion of the at least one component previously subjected to shot peening.
Abstract:
A method for creating an artifact for use with an optical three-dimensional measuring system includes steps of: (a) providing an artifact that comprises an inspection surface, which artifact is configured to be scanned by a non-contact sensor included in the optical three- dimensional measuring system, which artifact comprises at least one of a substantially spherical body and a turbine engine component, and which inspection surface comprises a surface of one of the substantially spherical body and the turbine engine component; (b) heating the artifact to a predetermined temperature; and (c) coating the inspection surface of the heated artifact with an approximately uniform coating of dry film lubricant.

Abstract:
A threaded joint for steel pipe formed of a pin and a box having a contact surface including threaded parts and a non-threaded metal contact part and capable of stably assuring a seizure resistance and an airtightness without applying compound grease thereto, wherein a solid lubricating film formed with lubricating powder (example: molybdenum disulfide) and organic or inorganic binder is formed on the contact surface of at least one of the pin and box, the ratio of the area occupied by the secondary particles of 15 to 60 mu m in equi-area equivalent diameter of the lubricating powder in the cross section of the solid lubricating film in thickness direction is 5 to 90%, and fiber-like filler (example: inorganic substance whisker) in addition to the lubricating powder is mixed into the solid lubricating film at the mass ratio of the fiber-like filler to binder of 0.01 to 0.5, whereby, particularly, the seizure resistance at high temperatures can be improved.
Abstract:
A sliding material exhibiting excellent initial compatibility, excellent sliding characteristics even under severe sliding conditions, especially excellent frictional characteristics and wear resistance under fluid lubrication, boundary lubrication and dry lubrication, and having a solid state lubrication coating film. The sliding material having a solid state lubrication coating film on a planar basic material is characterized in that a plurality of concentric grooves are made in the circumferential direction on the sliding surface and a ridge is formed between adjacent grooves.
