| Brass, Bronze | Endurakote® plating | 0.15 - 0.13 |
| Endurakote® plating | Endurakote® plating | 0.14 - 0.12 |
C. Adhesion｜附着力
Endurakote® 在标准弯曲测试或高热量环境下，不会从基材上片状剥落、开裂、崩裂、起皮或分离。其附着力足以承受球轴承和滚子轴承接触区域的极高压缩应力。
E. Corrosion Resistance｜耐腐蚀性
Endurakote® 可抵抗大多数 pH 4 到 11 范围内的有机和无机化合物腐蚀，但不包括硫酸和盐酸。基材孔隙率、化合物浓度和暴露时间会影响腐蚀，但 Endurakote® 可显著增强基材。
在严重盐雾试验和自来水浸泡试验中，Endurakote® 轴承钢的防锈能力等同于全硬化 AISI 440C 不锈钢。很多情况下，其耐腐蚀保护优于镉镀层、锌镀层、磷酸盐、铬酸盐、黑氧化或普通铬镀层。
