(4) The nature of the ❹: (4) The steel is 'depleted of steel at all times, especially: Taiwan II! In the harsh environment of the wet maritime monsoon, the "corrosion" problem is more serious than other countries. The advanced countries have long noticed the seriousness of "corrosion", and it is estimated that the damage caused by the anti-language is in Japan - about 3% of the nationals = Mao, (GNP). In the United States, this ratio is 4.2%, in the UK 3.5% 'West Germany is 3%' and Taiwan is far above the above ratio, such as 3.5% of Japan, we don’t know in 2〇〇1 I felt that I lost NT$333.0 billion (the gross domestic product in 2001 was about NT$915.13 billion). Therefore, advanced state-owned countries have established relevant anti-money technology research institutions to take various effective measures to avoid or reduce their losses. However, there seems to be no major institution in China to face this problem. Therefore, 'there can be seen everywhere because of the poor anti-corrosion technology or the anti-corrosion method error 201026892 - caused by the "rust rice" landscape, it is very sad" and the use of zinc has been used for more than 150 years, it is estimated that The total amount of steel that is protected by hot dip is about 2,000,000 10,000 tons per year. 'The maintenance value of human limited resources is hard to estimate. (Excerpted from the website of the Republic of China's Hot Dip Forum, httP://www.gaitw.org.tw/inf〇htm), currently used in Ersangwan for the use of hot-dip mines on the screws and nuts to form Mine: The layer has been used as a button for more than 30 years. However, since the hot dip must be carried out at a high temperature of about 500 C, it is a heat treatment operation, and the special workpiece is usually heat treated by tempering or Carburizing heat treatment to adjust the surface and core hardness, the workpiece through the quenching and tempering heat treatment will change the composition particles inside the workpiece, so that the workpiece material can reach the required grade requirements, so the heat treatment will strengthen the hardness of the workpiece and the internal organization of the workpiece. Stabilization, while carburizing heat treatment mainly uses carbon 70 to penetrate into the surface of the workpiece, so that the workpiece forms a carburized layer, and the surface layer of the workpiece is hardened, which has little effect on the hardness of the workpiece core, but the internal part of the workpiece is heat treated by quenching and tempering. The structure is stable, so it has little effect on the mechanical properties of the workpiece after hot dip plating. But for heat treatment carburizing work such as self-tapping screws or self-tapping screws The heat treatment of carburizing is used to adjust the hardness of the surface and the core. Secondly, because the carburized layer is thin, and the carburizing heat treatment has a small impact on the hardness of the core of the workpiece, the temperature of the hot dip galvanizing immersion plating and the immersion plating The length of time, as well as the subsequent cooling operations often lead to changes in the mechanical properties of the heat-treated carburized workpiece, which cannot meet the requirements of the finished product. Therefore, only 201026892 can use the electroplating method or the mechanical mineral zinc method to form the mineral layer, = containing zinc leaching method, Mechanical methods such as smear or zinc spray method ^ "The thickness of the galvanized layer formed by the plating method is limited and one electric method does not hold the a helmet, the upper part, the upper part, the difference" and the mechanical money, the zinc difference: I: point or mouth All have corner uniformity [= content Γ 防 # 效果 effect is not as good as hot leaching mine. 羑 ' 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 钻 钻 钻 钻 钻 钻 钻 钻The utility model provides a hot dip galvanizing method for treating a carburized workpiece, and the steps thereof are as follows: Α· The heat treatment of the carburized workpiece is performed before cleaning.

The above-mentioned pre-cleaning operation sequence is degreased by high temperature, washed with water, pickled and rusted, washed again, soaked with flux and dried by hot air.
