ALD原子层沉积技术的应用
硬盘
Smaller critical dimensions and more challenging topographies of magnetic recording heads have led to a need to replace conventional physical vapor deposition (PVD) coating technology with a more conformal coating method. ALD was selected as a new method to enable further scaling down. An additional benefit of ALD was the high quality of ultrathin insulating layers with low pinhole density. ALD AlOx has been used in read heads for several years, and ALD thin films and nanolaminates are being investigated for other applications in the read/write head process flow, such as trench filling, tunneling barriers, and encapsulation.
ALD is a powerful technology for this development work, as surface chemistry has an important role in the selection and optimization of materials, processes, and process conditions for electronic devices.

In one embodiment, an anti-corrosion electrode is formed to apply a voltage to the main magnetic pole piece during processing of the air bearing surface. This retards corrosion of the main magnetic pole piece. Since a conductor (anti-corrosion wire) connected to this anti-corrosion electrode is made of a nonmagnetic material, concentration of an external magnetic field into the main magnetic pole piece can be suppressed. Consequently, since the magnetic leakage field emitted from the main magnetic pole piece is reduced, erasure of the signal on the medium can be prevented. In addition, since the anti-corrosion wire is connected to the upper core, this wire can be formed in the same wiring layer as a wire which connects the coil to a write terminal, resulting in a simplified manufacturing process.申请人：Atsushi Kato,Tomohiro Okada,Masahiko Soga地址：Kanagawa JP,Kanagawa JP,Kanagawa JP国籍：JP,JP,JP更多信息请下载全文后查看。

压力容器的强度计算
第11章压力容器的强度计算本章重点要讲解内容：（1）理解内压容器设计时主要设计参数（容器内径、设计压力、设计温度、许用应力、焊缝系数等）的意义及其确定原则；（2）掌握五种厚度（计算壁厚、设计壁厚、名义壁厚、有效壁厚、最小壁厚）的概念、相互关系以及计算方法；能熟练地确定腐蚀裕度和钢板负偏差；（3）掌握内压圆筒的厚度设计；（4）掌握椭圆封头、锥形封头、半球形封头以及平板封头厚度的计算。
（5）熟悉内压容器强度校核的思路和过程。
第一节设计参数的确定1、我国压力容器标准与适用范围我国现执行GB150－98 “钢制压力容器”国家标准。
该标准为规则设计，采用弹性失效准则和稳定失效准则，应用解析法进行应力计算，比较简便。
JB4732-1995《钢制压力容器—分析设计标准》，其允许采用高的设计强度，相同设计条件下，厚度可以相应地减少，重量减轻。
其采用塑性失效准则、失稳失效准则和疲劳失效准则，计算比较复杂，和美国的ASME标准思路相似。
2、容器直径（diameter of vessel）考虑压制封头胎具的规格及标准件配套选用的需要，容器筒体和封头的直径都有规定。
对于用钢板卷制的筒体，以内径作为其公称直径。
表1 压力容器的公称直径（mm）如果筒体是使用无缝钢管直接截取的，规定使用钢管的外径作为筒体的公称直径。
表2 无缝钢管制作筒体时容器的公称直径（mm）3、设计压力（design pressure）（1）相关的基本概念（除了特殊注明的，压力均指表压力）工作压力P W：在正常的工作情况下，容器顶部可能达到的最高压力。
①由于最大工作压力是容器顶部的压力，所以对于塔类直立容器，直立进行水压试验的压力和卧置时不同；②工作压力是根据工艺条件决定的，容器顶部的压力和底部可能不同，许多塔器顶部的压力并不是其实际最高工作压力（the maximum allowable working pressure）。
③标准中的最大工作压力，最高工作压力和工作压力概念相同。

Corrosion of magnetic recording heads and media

Abstract Heads and media used in extremely high recording density hard-disk drives are protected against corrosion and wear by an ultrathin diamond-like or amorphous carbon overcoat. However, corrosion will occur if the ultrathin protective overcoat is porous or defective due to poor film deposition or is damaged tribologically. Disk media with ultrathin carbon overcoat subjected to accelerated environment (humidity, temperature and corrosive gas) testing were found to corrode along texture lines and at random pinholes via galvanic corrosion. Similarly, head pole materials also corrode at pinholes and the corrosion products were found to distribute across the poles and beyond after. Heads and media subjected to contact-start-stop (CSS) testing were more susceptible to corrosion. Clusters of corrosion spots and overcoat flaking or fracture were observed on wear track of the disk media. Overcoat fracture and damage is even more severe for the recording heads. Chemical analysis and imaging of the corrosion products using the time-of-flight secondary ion mass spectrometer (TOF-SIMS) and Auger electron spectrometer (AES) showed that the corrosion products are various oxides and hydroxides and or chlorides (if Cl is present) of Co from the magnetic storage layer and of Ni from the NiP plating layer or Ni and Fe for the recording heads. 2003 Elsevier Science Ltd.

has improved when the disk roughness has decreased much faster than carbon overcoat thickness. However, it is very challenging to produce ultrathin overcoats (Ͻ 3 nm) that are completely wetting and low in porosity especially in the presence of subtrate texture that is needed for magnetic orientation control. Often corrosion products are found distributed along such lines[4]. The presence of a hydrophobic lubricant layer on the protective carbon coat can also help to some extent in reducing corrosion. Similarly for the recording heads, where permalloy is used for the write poles, MnFe for the antiferromagnetic layer magnetoresitive (MR) sensors, is also very susceptible to corrosion. Various noble metal substitutes for Fe, such as Ir, Ni are used to reduced the increase the chemical corrosion potential[5]. Heads are also protected against corrosion by a carbon overcoat. The corrosion of heads and media is accelerated in the presence of humidity, elevated temperature and trace amounts of corrosive contaminants. The disk-drive is a rich source of contaminants that can be detrimental to its reliability and durability. Outgas compounds from polymeric foam components and pressure sensitive adhesives, ionic residues from improperly cleaned components, and ambient pollutants like sulfur dioxide, hydrogen sulfide, hydrogen chloride and various nitric
and nitrous oxides, for example, are all possible accelerators in the corrosion process. For ultrathin carbon overcoat, the repeated impact and sliding contact from the contact-start-stop (CSS) process potentially weakens the protective overcoat through fatigue wear, pitting, and delamination[6] as well as the depletion of lubricant on the disk surface. In this paper we will investigate the corrosion susceptibility of the carbon overcoated heads and disk media that have been subjected to tribological contact and wear. The distribution of corrosion spots and the chemical composition of the corrosion spots in and out of the wear or CSS track are also examined. 2. Experiment setup The thin film disk media used in this experiment has a topically applied Zdol lubricant with X1-P additive of 23 A thick, a carbon overcoat of 40 A and dual-layer CoCrTaPt/CoCr magnetic layer and a CrMo underlayer over the NiP plated Al substrate. Two types of negative pressure sliders, as shown in Fig. 1, were used. The sliders have an omega-shape air-bearing, one of them, Fig.
