A method for reducing and determining coefficient of friction of a mycelium for improving a plurality of mechanical properties of the mycelium. In the method, a first mycelium layer is contacted with an abrasive and pressure apparatus for smoothing and altering a microstructure of the mycelium. The smoothing of the mycelium microstructure reduces the coefficient of friction of the mycelium thereby enhancing the abrasion resistance of the mycelium. The coefficient of friction of the mycelium surface reduced through smoothing of the mycelium surface is determined utilizing a tilt angle mechanism.

A burnishing machine is provided in which both sides of a groove is machined by a single tool without changing the movement direction of a piston.

The burnishing machine, includes: a tip configured to press and process a process face; and a pressurizing unit configured to press the tip against the process face, the pressurizing unit including, a piston configured to reciprocate in a direction orthogonal to the tip, a cylinder portion that accommodates the piston such that the piston reciprocates; and a pressurizing mechanism configured to urge the tip to the process face at both timing of pushing the tip against the process face and pulling the tip against the process face by making the piston reciprocate.

A machining tool incorporates a shaft having a first end configured to fit into a machining collet. A cutting portion extends from a second end of the shaft. A residual stress inducer is located between the first and second ends and includes a torsion element joined to the shaft at a connection end. A carbide tip is present on a free end opposite the connection end and the torsion element is configured such that a selected rotational speed, altered from a normal cutting speed, causes the carbide tip of the torsion element to contact a workpiece surface.

Internal and external screw thread burnishing assemblies are provided. In the internal screw thread burnishing assembly, diametrically opposed removable cartridges carrying burnishing wheels are received in cavities of a support structure axially movable into the space circumscribed by the internal screw thread. Fluid pressure is utilized to forcibly translate the cartridges radially outwardly to place their burnishing wheels into burnishing engagement with the internal screw thread, with a spring structure resiliently biasing the cartridges toward retracted orientations thereof within the support structure. In the external screw thread burnishing assembly, burnishing wheels are carried on the outer ends of pivotally supported arms which may be pivoted by fluid pressure to drive the burnishing wheels into burnishing engagement with diametrically opposite portions of the external screw thread, with a spring structure resiliently biasing the arms pivotally away from one another.

An electromagnetic hammer device adapted to provide non-contact mechanical treatment of a material in planar items, cylindrical items, or tubular items including a conductor provided along a predetermined path within the material being treated and being supplied with a first pulsed current and a second linearly configured conductor or V-shaped conductor or conductive tube lined on top of conductor and being supplied with a second pulsed current, a layer of insulating material being lined intermediately between the first and second conductors. The simultaneous application of the first and second pulsed currents in the same direction results in exerting tensile forces onto the material and application of the currents in opposite directions results in exerting compressive forces therein. A pair of auxiliary conductors is preferably provided in each side of the second conductor, which provides adjustment of the angle in which the tensile or compressive forces are applied. A method for the mechanical treatment of a material using the hammer device.

Embodiments of the present disclosure provide surface treatment tools, methodologies, and/or repaired turbomachine components. A surface treatment tool according to the present disclosure can include a lathe assembly having a lathe chuck for receiving a component thereon, wherein the lathe chuck rotates the component about a first axis of rotation, and wherein the component includes an exposed axial target surface; and a sander or burnishing tool coupled to the lathe assembly and including a sanding or burnishing surface thereon, coupled to a drive system, wherein the sanding or burnishing surface rotates about a second axis of rotation substantially non-parallel with the first axis of rotation, such that the sanding or burnishing surface selectively contacts the target surface of the component to yield a polished target surface.
