The phosphor bronze (PB) is widely preferred in various engineering applications due to its high strength, toughness, fine grain size, low coefficient of friction, and better corrosion resistance. The present work is to investigate the effect of tungsten disulfide (WS₂) solid lubricant particle reinforcement in the phosphor bronze metal matrix composite (PBMC) through the mechanical and machining characteristics. The different variant of the composite is fabricated using stir casting technique by varying the volume percentage of WS₂ particle from 0% to10%. The prepared PBMC samples are subjected to mechanical and machining (boring and high-speed turning) characterizations. The hardness (Brinell hardness) and flexural strength of the composites are examined as per the ASTM standard. The surface roughness (Ra) of the PBMC sample is analyzed through the boring and high-speed turning operations by varying the spindle speed, feed rate, and depth of cut. The scanning electron microscope (SEM) is employed to confirm the uniform dispersion of the reinforcement particle through the microstructural analysis. The presence of WS₂ particles and other ingredients is ensured by X-ray diffraction analysis in the composites. The influence of WS₂ reinforcement particles on tool life is analyzed on the PBMC4 (PBMC with 8% WS₂) with the predefined machining parameters in the high-speed turning operation. The increase in WS₂ particle (0–10%) improves the hardness (11.85%) and flexural strength in PBMC4 as compared to PBMC1 (PBMC with 0% WS₂). At a higher spindle speed (1200 r/min), the Ra is reduced in PBMC1 as compared to 900 r/min, whereas the rest of the PBMC sample show higher surface irregularity at 1200 r/min.

磷青铜（PB）具有高强度，韧性，细粒度，低摩擦系数和更好的耐腐蚀性，因此在各种工程应用中被广泛首选。目前的工作是通过机械和机械特性研究二硫化钨（WS ₂）固体润滑剂颗粒在磷青铜金属基复合材料（PBMC）中的作用。使用搅拌铸造技术通过改变WS ₂的体积百分比来制造复合材料的不同变体粒子从0％到10％。对制备的PBMC样品进行机械和机械加工（镗削和高速车削）表征。按照ASTM标准检查复合材料的硬度（布氏硬度）和弯曲强度。通过改变主轴转速，进给速度和切削深度，通过镗削和高速车削操作分析PBMC样品的表面粗糙度（Ra）。扫描电子显微镜（SEM）用于通过微观结构分析确认增强颗粒的均匀分散。通过X射线衍射分析可确保复合材料中WS ₂颗粒和其他成分的存在。在PBMC4（含8％WS的PBMC上，分析了WS ₂增强颗粒对工具寿命的影响₂）在高速车削操作中具有预定义的加工参数。在WS增加₂相比PBMC1（PBMC与0％的WS粒子（0-10％）改善PBMC4硬度（11.85％）和挠曲强度₂）。在更高的主轴转速（1200 r / min）下，PBMC1中的Ra降低为900 r / min，而其余PBMC样品在1200 r / min下显示出更高的表面不规则性。
