연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

Embodiments of the present disclosure provide surface treatment tools, methodologies, and/or treated 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 is oriented along a second axis 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.

1. A surface treatment tool comprising: a lathe assembly having a lathe chuck configured to receive 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 oriented axially relative to the first axis of rotation;an axially-adjustable tool arm mechanically coupled to the lathe assembly and extending substantially in parallel with the first axis of rotation, such that the axially-adjustable tool arm is positioned proximate an outer circumference of the component;a sanding arm adjustably connected to the axially-adjustable tool arm, wherein the sanding arm extends radially inward from the axially-adjustable tool arm toward the first axis of rotation;a sander coupled to the sanding arm, wherein the sander includes a sanding surface extending along a second axis of rotation substantially perpendicular with the first axis of rotation, such that the sanding surface contacts the exposed axial target surface of the component during rotation of the component about the first axis of rotation; anda drive system coupled to the sander for rotating the sander about the second axis of rotation, and pressing the sander against the axial target surface of the component, to yield a polished target surface having a greater specific surface area and a reduced surface roughness during contact between the component and the sanding surface. 2. The surface treatment tool of claim 1, further comprising the component mounted on the lathe assembly, wherein the component includes a wheel flange, and wherein the target surface comprises a mating face of the wheel flange. 3. The surface treatment tool of claim 2, wherein the sanding surface is structured to increase a frictional coefficient of the axial target surface during contact with the component. 4. The surface treatment tool of claim 1, wherein the sander comprises a drum sander positioned circumferentially about the second axis of rotation. 5. The surface treatment tool of claim 1, further comprising a trimming tool coupled to the axially-adjustable tool arm wherein the trimming tool is independent from the sander, and wherein the trimming tool further includes: a trimming element extending radially inward from the axially-adjustable tool arm toward the component; anda rotatable coupler configured to adjust an angular orientation of the trimming element relative to the axially-adjustable tool arm. 6. The surface treatment tool of claim 1, wherein the axially-adjustable tool arm of the lathe assembly further includes a track for selectively aligning the sander with the axial target surface of the component. 7. A method for treating a component, the method comprising: rotating a target surface of a component about a first axis of rotation, the component being mounted on a lathe chuck oriented substantially along the first axis of rotation, wherein the target surface of the component includes an exposed axial target surface oriented axially relative to the first axis of rotation, and shaped to matingly engage an adjacent component;positioning an axially-adjustable tool arm proximate an outer surface of the component, wherein the axially-adjustable tool arm is mechanically coupled to a lathe assembly and extends substantially in parallel with the first axis of rotation;rotating a sanding surface of a sander about a second axis of rotation, wherein the second axis of rotation is substantially perpendicular with the first axis of rotation, and wherein the sander is adjustably connected to the axially-adjustable tool arm and extends radially inward from the axially-adjustable tool arm toward the first axis of rotation; andcontacting the sanding surface of the sander with the target surface of the component, during the rotating of the target surface about the first axis of rotation and the rotating of the sanding surface about the second axis of rotation, to yield a polished target surface having a greater specific surface area and a reduced surface roughness relative to a remainder of the component, wherein a frictional coefficient between the polished target surface and an adjacent component is greater than an initial frictional coefficient between the target surface and the adjacent component. 8.
