求翻译：在化学镀液中，加入PTFE复合粒子可以使得复合镀层硬度降低、孔隙率增加、耐腐蚀性降低，但是Ni-P-PTFE复合镀层具有良好的自润滑性，而且复合镀层与基体的结合力良好是什么意思？

In a chemical bath, join ptfe composite particles can make the composite coating hardness decreased, increased porosity, corrosion resistance, reduce the ni-p-ptfe composite coatings with good self-lubricating composite coating and the substrate binding

In the chemical nickel-fluid, to join PTFE composite particles can make composite coating hardness, porosity, and increase resistance to corrosion, but Ni - P - PTFE composite coating with a good self-lubricating, and composite coating and substrate combination of good

In the chemical plating fluid, joins the PTFE compound particle to be possible to cause the compound coating degree of hardness to reduce, the factor of porosity increases, the inoxidizability reduces, but the Ni-P-PTFE compound coating has the good self lubrication, moreover compound coating and th

In electroless plating solution, join the PTFE composite particles composite coating hardness reduction, increase in porosity, reduced corrosion resistance, but Ni-P-PTFE have good self-lubricating composite coatings and composite coatings and substrate adhesion good
