Title: Method for making a passivating coating based on one or more silicon compounds on a ceramic matrix composite reinforced with carbon fibres and ceramic matrix composite reinforced with carbon fibres with such coating
Inventor: CAVALLI LORENZO
IPC: C04B41/45
Filed: 2020-09-16
Abstract: The invention relates to a method for making a silicon compound-based passivating coating on a ceramic matrix composite reinforced with carbon fibres. The method comprises the following steps: a) providing at least one piece made in a ceramic matrix composite reinforced with carbon fibres; b) placing the piece to be coated in a closed chamber of an oven; c) placing in the closed chamber a predefined load of solid silicon avoiding direct contact between the silicon and the piece to be coated; d) heating the oven, maintaining inside the chamber predefined medium vacuum or low vacuum conditions, so as to generate from the silicon load vapours of silicon inside the closed chamber, which react with one or more substances present on the surface of the piece leading to the formation of a surface coating comprising composites of said one or more substances with the silicon; e) choosing the partial pressure of the vacuum, the temperature inside said closed chamber and the exposure times of the piece to the vapours of silicon so as to obtain a predefined thickness of the surface coating on said piece; and f) cooling the piece once the predefined thickness of the passivating coating has been reached.

Abstract: This application provides a fingerprint recognition module, a screen assembly, and an electronic device. The fingerprint recognition module is disposed below the screen assembly of the electronic device, and includes an LED, an image sensor, and a light shielding member. A light emitting surface of the LED faces the screen assembly and is used to emit an optical signal. A photosensitive surface of the image sensor faces the screen assembly and is used to receive an optical signal, where the optical signal received by the image sensor includes a fingerprint optical signal returned after being emitted by the LED to a finger, to generate a fingerprint image. The light shielding member is partially or entirely located between the LED and the image sensor, to block a part of signal light emitted by the LED. An optical signal emitted by the LED arrives at the image sensor after being reflected by the screen assembly, thereby causing interference to fingerprint information. In this application, a part of optical signals with relatively large emergent angles are blocked by using the light shielding member, so that optical signals reflected by the screen assembly can be reduced. In this way, interference to the fingerprint information is reduced, so that a fingerprint image with relatively high definition can be obtained.

Abstract: A folding knife comprises a blade 1 which has a pin 9 and is pivotally fastened to a locking plate 2 having an aperture for a pivot bushing. In a first variant, the folding knife comprises a pivot bushing 3 with a flange 4. In a second variant, the knife has a pivot bushing 17 with a flange 18, and, on the opposite side of the blade 1, there is a clamping bushing 19 with a flange 20, which interacts with the pivot bushing 17 by means of a tight fit. A tightening screw 7 is screwed into the pivot bushing 3 or 17. Mounted on both sides of the blade 1, on the pivot bushing 3 or 17, are washers 5 and 6 made of an anti-friction elastically deformable material having a compressive elastic modulus of not less than 800 MPa. The locking plate 2 and a cover plate 8 are fastened by the insertion of fastening screws 12 into corresponding apertures 13. A backspacer 11 is mounted in the gap between the plates 2 and 8. A liner 10 is mounted in the lower portion of the locking plate 2. The technical result is simpler assembly, an increased lifespan as a result of more efficient compensation of lateral and torsional forces on the blade, and repairability.
