Description
技术领域
本发明涉及体育活动用品高尔夫球具，特别涉及到高尔夫球杆球杆头的NQP局部硬度工艺。
背景技术
高尔夫球运动是一项绿色、健康、时尚的运动，因为它独特的魅力特点受到越来越多的人喜爱和普及，同样使用者对高尔夫球具的品质和种类的要求越来越高；
高尔夫球运动中，球具装备是高尔夫球运动中最重要的一环，球具装备由握柄、杆身、球杆头组成，其中球杆头是决定在击打高尔夫球时瞬间产生出柔顺的手感的关键所在，但球杆头的局部包括FACE面板、杆径部、底部，其不同的硬度和厚度要求是铁杆头制作工艺的主要因素；
目前市场上高尔夫球杆的球杆头的设计制作工艺为普通热处理，例如电镀、QPQ等，制作过程简单,适应用于传统的产品要求，对于职业球员的需求来说很不理想；
1、底部位置硬度为 550HV~650HV ，使耐磨度较低；
2、在高尔夫铁杆头FACE面板位置的ε相化合物层的厚度为10μm~20μm，因其厚度较厚，使FACE面部的硬度过高，球的飞行轨迹比较难以控制；
3、杆径部位置ε相化合物层厚度为10μm~20μm，导致材料因硬度过高容易产生表面脆裂；
因此,在现有技术下的铁杆头的硬度工艺的研发成为各品牌商技术研发和竞争的焦点。
发明内容
本发明在于提供一种高尔夫球杆的球杆头的NQP局部硬度工艺，使球杆头的底部、FACE面板、杆径部的硬度改变，以解决上述背景技术中的缺陷。
一种高尔夫球杆的球杆头的NQP局部硬度工艺，其中NQP工艺是Nitrogentreatment－Quench－Polish的缩写形式，该种技术是将高温与低温渗氮加上盐浴氧化的相接合工艺，该工艺用于高尔夫球杆头属于新兴的一种表面热处理技术；是指将高尔夫铁杆头局部不需加硬的部分用耐高温涂料保护，进行气氮处理，调整得到局部产品所需要的硬度。再放入两种性质不同的熔融盐浴中进行氮碳共渗，从而达到使高尔夫铁杆头表面局部改性的目的。
所述球杆头的NQP工艺分为以下多阶段进行：
第一阶段对需喷涂耐高温涂料进行局部保护，自然干燥；
第二阶段在550℃~580℃进行气氮150min~360min；
第三阶段是对球杆头进行表面清洁度处理；
第四阶段在550℃~565℃进行氮碳共渗10min~20min；
第五阶段进入365℃~385℃氧化25min~30min，之后直接水冷淬火；
第六阶段是对球杆头表面进行喷砂处理以获得表面清洁度；
第七阶段再次进入365℃~385℃左右氧化25min~30min，再用水冷却；
第八阶段是再次对球杆头进行喷砂处理以获得要求的表面清洁及光泽度，得到符合产品特性的高尔夫铁杆头。
本发明的有益效果是：本发明工艺的高尔夫球杆头，其同一材料经处理后有局部软硬度产生，与现有技术相比；
1、底部形成了25μm~35μm的ε相化合物层，使底部增加了硬度，硬度为850HV~ 980HV，在砂坑击打测试时比传统工艺耐磨程度增加5~10倍的耐磨度;
2、球杆头的FACE面部的ε相化合物层，厚度只有1μm~2μm，这样职业球手在击球时可以更好的控制球的飞行轨迹，实现精准控球；
3、杆径部ε相化合物层厚度也只有1μm~2μm，其优点是可供不同高尔夫职业选手在使用其产品时，可改变产品的角度，而不会导致材料因硬度过高产生脆裂；
因此用该工艺所产生出的高尔夫铁杆头，其优异的适用特性明显优于电镀和QPQ所带来的价值。

一种高尔夫球杆杆头的NQP局部硬度工艺,具体步骤。
1、第一阶段对不需要硬度的地方喷涂耐高温涂料进行局部保护，自然干燥；
工艺操作：用电工胶布将球杆头需要增加硬度的区域（例如底部、FACE面部、杆径部）保护起来，用喷漆枪进行喷涂，将不需要增加硬度的区域喷涂耐高温涂料，然后置于挂具上（球杆头置于挂具上，以下的流程步骤中均随挂具运行。）自然干燥，待耐高温涂料干燥后撕掉电工胶布。
2、第二阶段在550℃~580℃进行气氮150min~360min；
工艺操作：使用气氮炉进行气氮作业，挂具通过输送装置送入气氮炉内气氮，气氮炉升温至炉内温度为500℃~580℃后,保持气氮时间为150min~360min, 然后关闭气氮炉，炉内降温，使球杆头底部形成25~35μm的氮化层。
3、第三阶段是对高尔夫铁杆头进行表面喷砂清洁度处理；
工艺操作：挂具移出气氮炉用喷砂机进行喷砂，清除表面杂质。
4、第四阶段在550℃~565℃进行氮碳共渗10min~20min；
工艺操作：使用液氮炉进行气氮作业，保持液氮炉内温度550℃~565℃，将挂具上的送入进行液氮炉内气氮，气氮时间为10min~20min，使球杆头的FACE面板、杆径部达到1~2μm的氮化层。
5、第五阶段进入365℃~385℃氧化25min~30min，之后直接水冷淬火；
工艺操作：使用氧化炉进行氧化作业，保持氧化炉内温度为365℃~385℃，将氮碳共渗完成的球杆头从液氮炉内直接输送至氧化炉内，氧化时间为25min~30min，将整个球杆头氧化成为黑色，从氧化炉内输送出后直接放入冷水中淬火。
6、第六阶段是对高尔夫铁杆头表面进行喷砂处理以获得表面清洁度；
工艺操作：用喷砂机进行喷砂，清除表面杂质。
7、第七阶段再次进入365℃~385℃氧化25min~30min，再用水冷却；
工艺操作：使用氧化炉进行氧化作业，保持氧化炉内温度为365℃~385℃,将挂具输送到氧化炉内氧化，氧化时间为25min~30min，将球杆头氧化成为黑色，挂具移出氧化炉，放入冷水中冷却。
8、第八阶段是再次对球杆头进行喷砂处理以获得要求的表面清洁及光泽度，得到符合产品特性的高尔夫球杆头；
工艺操作：用喷砂机进行喷砂，清除表面杂质，以获得表面清洁度符合外观要求。
本发明NQP工艺的工作原理为：NQP的主要成分由气氮化与盐浴氮化组成，分由碳酸盐和尿素相接合而成，加之中途利用耐高温涂料进行干预，使它们在高温下相互反应生成氰酸根（CNO-）。CNO-再分解出C、N活性原子，使其渗入工件表面，形成局部产生2~35μm的ε相化合物。ε相化合物在随后的氧化盐浴（强碱和硝酸盐）中形成Fe3O4氧化膜，同时零件从氮化盐浴中黏附的含有CN-氰化物离子的有毒物质被氧化成无毒的碳酸盐CO32-和氰酸盐CNO-。轻微机械抛光的目的是降低零件表面在氮化和氧化盐浴中处理而变高了的表面粗糙度值。由于抛光会破坏零件表面氧化膜，从而使耐腐蚀性下降，故再进行一次氧化处理，以重新在零件表面形成一层均匀、致密的Fe3O4薄膜。
本发明, 一种高尔夫球杆的球杆头的NQP局部硬度工艺,其工艺过程,均在井式炉中完全,工艺过程安全无污染,降低成本; 成型后的球杆头耐磨性好、提高扣球的精准度、延长产品的使用期限，给厂家带来经济效益，给球员带来良好的使用体验。
以上所述，仅是本发明的较佳实施例，并非对本发明的技术范围作任何限制，本行业的技术人员，在本技术方案的启迪下，可以做出一些变形与修改，凡是依据本发明的技术实质对以上的实施例所作的任何修改、等同变化与修饰，均仍属于本发明技术方案的范围内。
