Machine and Process Control 设备与工艺控制

 

To improve the process of thermal spraying, our enterprise has specialized in the machine and process control. A core component of our coating equipment is the PC / PLC - combination for control and regulation: All relevant parameters are maintained to constant values and visualized as a function of time with defined alarm barriers. Apart from easy data handling (EXCEL), the PC allows the integration of additional software (for example permanent calculation of coating costs, process monitoring and so on). As the PC is only the working surface, there is no danger of a machine stand still caused by the PC.

 

为了提高热喷涂工艺，我们企业专注设备研发及工艺控制。涂层设备的核心组成是PC/PLC—用来联合控制和调节。所有相关参数保持为恒定值，并以时间函数的形式显示，并定义报警屏障。除处理简单的（EXCEL）数据外，PC还可以允许更多的软件集成（例如持续计算涂层成本，以及过程检测等。由于电脑只是工作表面，没有机器设备的危险是由PC引起的。

 

Process control of thermal spraying热喷涂的工艺控制

 

Modern thermal spray operation is based on the coordination of the plasma plume or flame characteristics and powder properties. A central controller is needed which is linked with all the components of the spraying system.

 现代热喷涂操作的基础是协调等离子体或者焰流特性及粉末性能，必须通过一个中央控制器来连接喷涂系统所有组件。

 

The core element for the process control by Medicoat is a PC in combination with a programmable logic controller (picture 1). The PLC proved to be the best solution for an automatic spraying process based on parameter sets stored in the E-PROM. The PC is however much more powerful in data registration, storage and visualisation which are needed for a certified coating production. Newly developed software enables us to make a link between the PLC and the PC. For the communication with the individual components Profibus DP is used. An optimised process performance with high stability and reproducibility is the result.

Medicoat工艺控制的核心元件是带有可编程序逻辑控制器的PC（见图1）。这个可编程序逻辑控制器（PLC）基于参数设置存储在E-PROM，是自动喷涂工艺理想的解决方案。而PC则在涂层生产中的数据录入、存储和可视化具有优势。开发的软件使我们可以轻松地将PLC和PC连接起来，采用Profibus DP进行单个部件的通信。故此拥有稳定性和重复性的工艺性能。

A specific property of our central process control is the package of security, which guarantees high availability under production conditions.

 我们的中心工艺控制器的一个特定性能是安全软件包，拥有高可用性/可靠性。

 

·       Every electrically measurable actual value is combined with an alarm in 3 steps of sensitivity: information, advice and constraint.

每个电测量的实际值与报警器的3个级别的灵敏度相结合：信息，警告和限制。

 

·       The permanent registration of all quality related spraying parameters, displayed as a function of time and printed out after the coating process is completed, is a very useful pre-warning in correlation to the tolerance range that have been defined for each parameter. Beside the constance in operation a significant prolongation of the lifetime of important parts and components is the result.

有关喷涂参数所有质量的永久录入，时间函数的展示和喷涂完成后打印，对每一个参数所定义的公差范围是有用的预警。因此除了在操作中的不变性，对重要部件和零件使用寿命也有相应的延长。

 

·       Servicing and recalibration by phone is done by means of a modem with secure internet connection.

凭借安全的因特网连接，可以通过电话来进行维修和再校准。

 

·       The data generated by the PLC during the spraying process fulfil the FDA requirement. The print-out of the data registration of the quality related spraying parameters as a function of the spraying time is accepted as process documentation.

在喷涂过程中，由PLC生成数据可满足FDA要求。与质量相关的喷涂参数的数据登记的打印输出以喷涂时间为函数被作为工艺文件存档。

 Also please consider the tensile adhesion strength for HA (40 MPa) due to the balance between our HA-powder and the spraying recipe.

由于我们HA粉末和喷涂配方之间的平衡，需同时考虑HA（40 Mpa）粘附拉伸强度

 

The roughness of the coating depends on the selected Ti-powder for the Ti-coating structure between the initial dense Ti-bond coat and the final HA-to coat.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Our business relationship in medical application is divided into 2 parts. One part is coating production for the implant producer the other in equipment for the in-house coating production of the implant producer.

我们在医疗行业的业务分为两部分，一部分是为骨植入生产商提供涂层生产，另外一部分是用为骨植入生产商提供涂层生产的设备。
