表面结构

[中文适用范围]： 该 SAE 标准涉及固体材料表面的几何不规则性。它为不同程度的粗糙度和波纹度以及多种铺设类型建立了明确的分类。它还提供了一组用于图纸@和规格@报告@等的符号。粗糙度和波纹度的范围分为多个步骤@，并且一般的铺设类型由类型特征确定。本标准没有定义什么程度的表面粗糙度和波纹度或什么类型的铺设适合任何特定目的。它没有具体说明获得或产生任何程度的此类违规行为的方式。它也不涉及其他表面质量，例如光泽@外观@颜色@耐腐蚀性@耐磨性@硬度@微观结构@和吸收特性，这些特性中的任何一个都可能是特定应用中的主要考虑因素。一般来说，表面的特性非常复杂。尽管表面不规则性的高度@宽度@长度@形状@和方向在特定应用中都可能具有实际重要性@，但本标准仅涉及它们的高度@宽度@和方向。 [外文原描述]： This SAE Standard is concerned with the geometrical irregularities of surfaces of solid materials. It established definite classifications for various degrees of roughness and waviness and for several varieties of lay. It also provides a set of symbols for use on drawings and in specifications, reports, and the like. The ranges for roughness and waviness are divided into a number of steps, and the general types of lay are established by type characteristics.This standard does not define what degrees of surface roughness and waviness or what type of lay are suitable for any specific purpose. It does not specify the means by which any degree of such irregularities may be obtained or produced. Neither is it concerned with the other surface qualities such as luster, appearance, color, corrosion resistance, wear resistance, hardness, microstructure, and absorption characteristics, any of which may be governing considerations in specific applications.Sufaces, in general, are very complex in character. Although the height, width, length, shape, and direction of surface irregularities may all be of practical importance in specific applications, this standard deals only with their height, width, and direction.Cross Reference: ANSI/ASME/B46.1
