Three different woods (lignum vitae; black fiber palm; spruce) were investigated regarding their friction and wear properties under abrasion and sliding. For the abrasive wear against silicon carbide paper, the palm wood gave the lowest removal of material, especially under an orientation of the black fibers normal to the contact region (on R–T-plane in R-direction). At the same time, this material had the highest anisotropy. Slightly less abrasion resistant was lignum vitae, whereas spruce was most easily abraded. This can be considered as an indication that spruce can easily be machined. Under sliding conditions against smooth steel, a similar tendency, but at much lower wear rates compared to abrasion, was found. The relatively high coefficient of friction under dry sliding allows the use of these woods as friction materials, for example in brakes. Additional lubrication of the two best woods, lignum vitae and black fiber palm, by soaked sunflower oil brought the coefficient of friction to a much lower level, so that the use of these woods as bearing materials in various applications is promising.

研究了三种不同的木材（维塔尼亚木，黑纤维棕榈，云杉）在摩擦和滑动下的摩擦和磨损性能。对于碳化硅纸的磨料磨损，棕榈木去除的材料最少，尤其是在垂直于接触区域（在R方向的R–T平面上）的黑色纤维的定向下。同时，这种材料具有最高的各向异性。木质木履的耐磨性稍差，而云杉则最容易磨损。这可以认为是易于加工云杉的指示。在对光滑钢的滑动条件下，发现了类似的趋势，但是与磨损相比磨损率要低得多。干滑下相对较高的摩擦系数允许将这些木材用作摩擦材料，例如刹车。用浸泡过的葵花籽油对两种最佳木材（木麻和黑纤维棕榈）进行额外的润滑，使摩擦系数降低到很低的水平，因此在各种应用中将这些木材用作轴承材料是有希望的。
