Title (EN) MANUFACTURING METHOD FOR HARD VALVE CONNECTOR
(FR) PROCÉDÉ DE FABRICATION D'UN RACCORD DE SOUPAPE DUR
(ZH) 一种硬质阀门连接件的制备方法
Abstract:
(EN) A manufacturing method for a hard valve connector, comprising the following steps: 1) material selection: a hard alloy tungsten steel of the grade of YL10 series is selected; 2) blank processing; 3) the surface of a crude valve connector undergoes grinding, polishing, ultrasonic cleaning, and drying; 4) a valve connector is placed in a vacuum chamber, when the degree of vacuum reaches 6 × 103 Pa, argon is introduced until 2 Pa, a direct current negative bias is added until -150 V, a sample undergoes glow cleaning for 10 min, and then goes into a thin film deposition process; and 5) the hard valve connector is acquired when the thin film deposition is completed. The hard valve connector manufactured per the manufacturing method is provided with increased hardness, not prone to damages, and applicable in relatively harsh external environments, and has a certain degree of corrosion resistance and high temperature resistance.
(FR) L'invention concerne un procédé de fabrication d'un raccord de soupape dur, comprenant les étapes suivantes : 1) la sélection de matériau : un acier tungstène en alliage dur du grade de la série YL10 est choisi ; 2) le traitement d'ébauche ; 3) la surface d'un raccord de soupape brut subit un meulage, un polissage, un nettoyage par ultrasons et un séchage ; 4) un raccord de soupape est placé dans une chambre sous vide ; lorsque le degré de vide atteint 6 × 103 Pa, de l'argon est introduit jusqu'à 2 Pa ; une polarisation négative de courant continu est ajoutée jusqu'à -150 V ; un échantillon subit un nettoyage par incandescence pendant 10 min, puis passe dans un traitement de dépôt de film mince ; et 5) le raccord de soupape dur est obtenu lorsque le dépôt de film mince est achevé. Le raccord de soupape dur fabriqué selon le procédé de fabrication est doté d'une dureté accrue, n'est pas sujet à des dommages, et est applicable dans des environnements externes relativement difficiles, et présente un certain degré de résistance à la corrosion et de résistance aux températures élevées.
(ZH) 一种硬质阀门连接件的制备方法,包括如下步骤;1)选材,选择牌号为YL10系列的硬质合金钨钢;2)坯料加工;3)对粗制阀门连接件表面进行研磨、抛光、超声清洗、干燥;4)将阀门连接件放入真空室内,待真空度达到6×103Pa后,通入氩气到2Pa,加直流负偏压至-150V,对样品进行辉光清洗10min;然后进入薄膜沉积过程;5)完成薄膜沉积后获得硬质阀门连接件。该制备方法制成的硬质阀门连接件具有较高的硬度不易损坏,适用于比较恶劣的外部环境,具有一定的抗腐蚀,抗高温的性能。
