Surface finish (original) (raw)
Struktura povrchu (také textura povrchu) je souhrnný termín, označující geometrické odchylky povrchu od jeho ideálního tvaru. Je výsledkem způsobu obrábění, hloubky stop po nástroji apod. Jedná se také o prohlubeniny (rýhy, trhliny), vyvýšeniny (vyboulením, otřepy), nebo plošné nedokonalosti (eroze, koroze). Podle velikosti nerovností se člení na 3 složky: * drsnost povrchu * vlnitost povrchu * základní profil

Podle velikosti nerovností se člení na 3 složky: * drsnost povrchu * vlnitost povrchu * základní profil (cs) L'acabat superficial o textura superficial, és la naturalesa d'una superfície tal com es defineix per les tres característiques de disposició o marca de mecanitzat, rugositat superficial i ondulació. Comprèn les petites desviacions locals d'una superfície respecte a l'ideal perfectament pla (un pla real). La textura superficial és un dels factors importants que controlen la fricció i la formació de capes de transferència durant el lliscament. S'han fet esforços considerables per estudiar la influència de la textura superficial sobre la fricció i el desgast durant les condicions de lliscament. Les textures superficials poden ser isòtropes o anisòtropes. De vegades, es poden observar fenòmens de fricció per lliscament durant el lliscament, depenent de la textura de la superfície. Cada procés de fabricació (com els molts tipus de mecanitzat ) produeix una textura superficial. El procés normalment s'optimitza per garantir que la textura resultant sigui utilitzable. Si cal, s'afegirà un procés addicional per modificar la textura inicial. Aquest últim procés pot ser mòlta (tall abrasiu), polit, lligat, granallat abrasiu, rectificat, mecanitzat per descàrrega elèctrica (EDM), fresat, litografia, gravat industrial / fresat químic, texturat làser o altres processos. (ca) Die Textur ist eine Beschreibung der Beschaffenheit von Oberflächen, die ursprünglich aus der Textilindustrie stammt. (de) Surface finish, also known as surface texture or surface topography, is the nature of a surface as defined by the three characteristics of lay, surface roughness, and waviness. It comprises the small, local deviations of a surface from the perfectly flat ideal (a true plane). Surface texture is one of the important factors that control friction and transfer layer formation during sliding. Considerable efforts have been made to study the influence of surface texture on friction and wear during sliding conditions. Surface textures can be isotropic or anisotropic. Sometimes, stick-slip friction phenomena can be observed during sliding, depending on surface texture. Each manufacturing process (such as the many kinds of machining) produces a surface texture. The process is usually optimized to ensure that the resulting texture is usable. If necessary, an additional process will be added to modify the initial texture. The latter process may be grinding (abrasive cutting), polishing, lapping, abrasive blasting, honing, electrical discharge machining (EDM), milling, lithography, industrial etching/chemical milling, laser texturing, or other processes. (en) Textuur, oppervlaktetextuur, oppervlakte topografie of oppervlaktestructuur (Engels: texture of surface finish) is de ligging (richting), ruwheid en golving van het materiaal van een oppervlak. Dit fysische fenomeen is in feite een benaming voor de oneffenheden in een oppervlakte. Een perfect glad oppervlak is dan ook textuurloos. (nl) Textura é o aspecto de uma superfície ou seja, a "pele" de uma forma, que permite identificá-la e distingui-la de outras formas.Quando tocamos ou olhamos para um objeto ou uma superfície sentimos se a sua pele é lisa, rugosa, macia, áspera ou ondulada. A textura é, por isso, uma sensação visual ou tocável. Texturas de certos objetos ajudam em sua identificação. (pt) Ytfinhet är ett mått eller karaktären på en ytas släthet eller grovhet. Ytfinhet består i sin tur av tre olika delar: , ytjämnhet och bearbetningens upplägg. (sv) 表面纹理（英語：surface finish）是物质界面的性质，由地形（lay）、表面粗糙度（surface roughness）、起伏度（waviness）三个特征定义。当表面并非理想的光滑平面，而是有局部的微小偏差时，这些偏差就组成了表面纹理。 表面纹理是决定摩擦力的重要因素，并在层间滑动时传递层的信息。对于不同滑动条件下表面纹理对摩擦力和磨损的影响，有可观的研究。表面纹理可以是各向同性的，也可以是各向异性的。当表面具有某些纹理时，在滑动中能观察到粘滑摩擦现象。 (zh) |
