The company will supply Airbus with portable laser peening
system, complete with laser, beam delivery, tooling and automation controls, for use at Airbus facilities.
was looking for a new peening
system for treating the toothed surface areas of different gear shafts, their specifications called for compressive stress values, which can normally only be safely achieved in compressed air systems.
Straaltechniek International BV, founded in 1982, develops and builds complete installations for shot peening
and high-end blasting applications, and is the leading supplier of installations and services in the field of surface treatment.
The carburizing and shot peening
are respectively selected as thermochemical and mechanical methods since they are the versatile surface strengthening treatments commonly used in the automotive industry.
Finally, Y factors from "edge repaired + shot peened T-butt" specimen are expected to be lower than Y factors determined from "edge repaired T-butt" specimen, since both specimens have the same notch repair geometry; thus SCFs are the same but induced compressive stresses by shot peening
tend to inhibit crack initiation and crack propagation until a certain depth.
Machine hammer peening
is based on the oscillating movement of an axially guided ram with a tool tip on its end (mostly spherical in shape), which periodically comes in contact with the workpiece.
The surface before and after shot peening
and the electron back-scattered diffraction (EBSD) result of raw sample were observed by scanning electron microscope (FESEM, JSM-7800F).
And alluding to Laser shock peening
(LSP), it is an inventive surface treatment method which makes compressive remaining stresses close to the surface, in this way created fatigue show of metallic elements [7, 8].
The RS present may arise from each step in the fabrication of the spring: extruding the wire (or rolling of the flat stock if applicable), any heat treatment applied, any coiling or forming, the machining of additional features, shot peening
, heat-setting, and even a paint bake cycle.
In addition, post-delubrication peening
, also known as PDP, contributes to eliminating surface and near-surface micro porosity on finished products, thus significantly reducing potential crack initiation sites at or near the surface and, consequently, improving the performance of the component under dynamic loading in operation .
Haraoka: Would it be possible for peening
to be applied to more high-technology sectorsWatanabe: Yes.
