标准号: ASTM B600—11 英文标准名称: Standard Guide for Descaling and Cleaning Titanium and Titanium Alloy Surfaces 国别: 标准类型: 美国材料实验协会标准 发布日期: null 实施日期: 2011-09-01 批准日期: null 发布单位: 起草单位: 标准状态: 废止 中文主题词: 英文主题词: 摘要: This guide covers a cleaning and descaling procedure useful to producers, users, and fabricators of titanium and titanium alloys for the removal of ordinary shop soils, oxides, and scales resulting from heat treatment operations and foreign substances present as surface contaminants. It is recommended that the materials shall be subjected to soil removal prior to heat treatment or application of acid treatment. Mechanical descaling methods such as sandblasting, shot blasting, and vapor blasting may be used to remove hot work scales and lubricants from titanium surfaces. Recommended post treatment of shot or abrasive blasted titanium surfaces may include acid pickling to ensure complete removal of surface contaminants. For chemically milled materials, salt bath conditioning may be required to remove the oxygen-contaminated layer. Acid etching treatment may be required following mechanical abrading or chemical conditioning of materials to completely clean the surface. 中国标准分类号: 国际标准分类号: 失效标准号: 页数: 3
