化学沉积Ni-P涂层可以抑制碳钢的热膨胀。镀后样品直径仅增加3%。衬底的热膨胀线性系数（CTE）由16 ppm/K降至12.68 ppm/K，降低率为20.72%。在613 K时，Ni-P涂层发生了体积收缩的结晶，这部分抵消了基体的热膨胀，从而产生了较小的CTE，这被称为结晶补偿机制。晶化后，在涂层与基体界面处形成以fei3为主的扩散层，FeNi3是NiFe Invar合金的初级相之一。该扩散层在抑制铁基体热膨胀中起关键作用，称为扩散层抑制机制。这些发现原则上适用于所有的亚铁合金，从而为降低亚铁合金的cte提供了一种潜在的简便方法。
The thermal expansion of carbon steel can be inhibited by electroless deposited Ni-P coating. The diameter of sample increases by only 3% after plated. The linear coefficient of thermal expansion (CTE) of the substrate is decreased from 16 ppm/K to as low as 12.68 ppm/K with a reduction rate of 20.72%. At 613 K, Ni-P coating crystallizes with a volume shrinkage which partly counteracts the thermal expansion of the substrate and then induces a small CTE, which is named crystallization compensation mechanism. After crystallization, a diffusion layer composed mainly of FeNi3, one of the primary phases of NiFe Invar alloys, generates in-situ at the interface of coating and substrate. This diffusion layer plays a key role in inhibiting the thermal expansion of iron substrate, which is named diffusion-layer inhibitory mechanism. These findings are, in principle, applicable to all the ferrous alloys so that a potential easy way can be promoted to decrease the CTEs of ferrous alloys.
